Essential Question
How Do You Name a Point on a Coordinate Grid?

A.
A map shows the locations of landmarks and has guides for finding them. In a similar way, a coordinate grid is used to graph and name the locations of points in a plane.
Envision Math Common Core Grade 5 Answer Key Topic 14 Graph Points on the Coordinate Plane 7.1

You can use ordered pairs to locate points on a coordinate grid.
Envision Math Common Core Grade 5 Answer Key Topic 14 Graph Points on the Coordinate Plane 7.2

B.
A coordinate grid has a horizontal x-axis and a vertical y-axis. The point at which the x-axis and y-axis intersect is called the origin.
Envision Math Common Core Grade 5 Answer Key Topic 14 Graph Points on the Coordinate Plane 7.3

C.
A point on the grid is named using an ordered pair of numbers. The first number, the x-coordinate, names the distance from the origin along the x-axis. The second number, the y-coordinate, names the distance from the origin along the y-axis.
Envision Math Common Core Grade 5 Answer Key Topic 14 Graph Points on the Coordinate Plane 7.4

Higher Order Thinking Point C is located at (10, 3) and Point D is located at (4,3). What is the horizontal distance between the two points? Explain.

Answer:
The distance between the points is (6, 0).

Explanation:
In the above-given question,
given that,
point C is located at (10, 3).
point D is located at (4, 3).
10 – 4 = 6.
3 – 3 = 0.
so the distance between the points is (6, 0).

Question 22.
Laurel buys 3 balls of yarn. Each ball of yarn costs $4.75. She also buys 2 pairs of knitting needles. Each pair costs $5.75. She pays for her purchase with two 20-dollar bills. What is her change?

Answer:
The change is $14.25.

Explanation:
In the above-given question,
given that,
Laurel buys 3 balls of yarn.
Each ball of yarn costs $4.75.
She also buys 2 pairs of knitting needles.
Each pair costs $5.75.
3 x $4.75 = $14.25.
$5.75 x 2 = $11.5.
$14.25 + $11.5 = $25.75.
20 x 2 = 40 dollar bills.
40 – 25.75 = $14.25.

The missing coordinates are (5, 200).

Explanation:
In the above-given question,
given that,
the points are (20, 800), (15, 600), (10, 400).
20 – 5 = 15.
15 – 5 = 10.
10 – 5 = 5.
800- 200 = 600.
600 – 200 = 400.
400 – 200 = 200.
so the missing coordinates are (5, 200).

Question 4.
Envision Math Common Core 5th Grade Answers Topic 14 Graph Points on the Coordinate Plane 12.9

Answer:
The missing coordinates are (900, 800).

Explanation:
In the above-given question,
given that,
the ordered pairs are (1500, 1200), (1200, 1000), (600, 600), and (300, 400).
on x-axis subtract 300.
1500 – 300 = 1200.
1200 – 300 = 900.
900 – 300 = 600.
600 – 300 = 300.
on y-axis subtract 200.
1200 – 200 = 1000.
1000 – 200 = 800.
800 – 200 = 600.
600 – 200 = 400.
so the missing coordinates are (900, 800).

subtract 100 on x-axis.
subtract 100 on y-axis.
600 – 100 = 500.
500 – 100 = 400.
400 – 100 = 300.
300 – 100 = 200.
200 – 100 = 100.
so the missing coordinates are (200, 150).

Question 2.
Write two ordered pairs with x-coordinates greater than 10 that are on the line.

Answer:
The two ordered pairs are (10, 5), and (12, 6).

Explanation:
In the above-given question,
given that,
the points on the x-axis are 2, 4, 6, and 8.
the points on the y-axis are 1, 2, 3, and 4.

6 + 2 = 8.
1 + 1 = 2.
2 + 1 = 3.
3 + 1 = 4.
4 + 1 = 5.
so the two ordered pairs are (10, 5), and (12, 6).

Question 9.
How is graphing (0, 12) different from graphing (12, 0)?

Answer:
(0, 12) is different from (12, 0).

Explanation:
In the above-given question,
given that,
the ordered pairs are (0, 12) and (12, 0).
(0, 12) is on the y-coordinate.
(12, 0) is on the x-coordinate.

Topic 14 Performance Task

Digging for Dinosaur Bones
Omar’s mother is a paleontologist. She digs up and studies dinosaur bones. Omar is helping at the dig site.

Question 1.
The Dinosaur Bone Dig 1 grid shows the location of the tent and the triceratops skull Omar’s mother found.
Part A
What ordered pair names the location of the triceratops skull? Explain how you know.
Envision Math Common Core 5th Grade Answer Key Topic 14 Graph Points on the Coordinate Plane 80.1
Part B
omar found a leg bone at (4, 12). Graph this point on the coordinate grid and label it L. Explain how you located the point using the terms origin, x-coordinate, x-axis, y-coordinate, and y-axis.
Part C
Next, Omar dug 3 meters east and 1 meter south from the leg bone. Graph a point where Omar dug and label it A. What ordered pair names the point?

Answer:
Part A: (6, 2).
Part B: (4, 12).
Part C: (7, 13).

Explanation:
In the above-given question,
given that,
Omar found a leg bone at (4, 12).
Omar dug 3 meters east and 1 meter south from the leg bone.
4 + 3 = 7.
12 + 1 = 13.
so part C is (7, 13).

Question 2.
Omar’s mother started at the triceratops skull. She kept moving east 1 meter and north 2 meters to dig for more dinosaur bones. Complete the table and the graph to find how far north she was when she was 11 meters east of the tent.

Answer:
When she was 11 meters east of the tent, the far = 6.

Explanation:
In the above-given question,
given that,
Omar’s mother started at the triceratops skull.
She kept moving east 1 meter and north 2 meters to dig for more dinosaur bones.
(4, 12) is the ordered pair given?
4 + 1 = 5.
12 + 2 = 14.
(5, 14) is the ordered pair.
11 – 5 = 6.
so when was 11 meters east of the tent, the far is 6 meters.
Part A
Complete the table of ordered pairs.

Part C
How far north was Omar’s mother when she was 11 meters east of the tent? Explain how to use the graph to solve and why your answer makes sense.

Answer:
The ordered pairs are (6, 2), (7, 3), ( 8, 4), and (9, 5).

Explanation:
In the above-given question,
given that,
East of the tent in meters is given.
they are 6, 7, 8, and 9 meters are given.
the first ordered pair is (6, 2) is given.
so the ordered pairs are (7, 3), (8, 4), and (9, 5).
when she was 11 meters east of the tent is (11, 7).
