Identifying and Plotting Points on Coordinate Grids

Look at the coordinate grid with labeled points. Which is the ordered pair for Point Y?

• (4, 5)

• (4, 9)

• (7, 9)

• (9, 4)

Answer explanation

Point Y is located at (4, 9) on the coordinate grid, where 4 is the x-coordinate and 9 is the y-coordinate. This matches the correct answer choice (4, 9).

Byron is playing Minecraft. He needs to find the Ender Dragon at the point (5, 2). Which point marks the location of the creature?

• M

• N

• Q

Answer explanation

Point N is located at (5, 2) on the coordinate grid, where Byron would need to move right five from the origin (as it's the x-coordinate) and then up 2 (as it's the y-coordinate).

What is the ordered pair for Point Z on the coordinate grid?

Answer explanation

Point Z is located 9 places away from the origin and 1 place up.

Each year, Paloma recorded the height of a tree that she planted when she was 4 years old. What does the point (1, ?) represent on this graph?

• Year 1, height 4 feet

• Year 1, height 5 feet

• Year 1, height 6 feet

• Year 2, height 5 feet

Answer explanation

The point (1, ?) indicates the height of the tree in Year 1. The correct choice, 'Year 1, height 5 feet', shows the height recorded for that year, making it the accurate representation of the data.

What will be the height of the tree after 7 years if the pattern continues?

• 9 feet

• 10 feet

• 11 feet

• 12 feet

Answer explanation

The Tree Growth graph shows a consistent increase in height. After 6 years, the height is 10 feet, and it grows by 2 feet each year. Therefore, after 7 years, the height will be 12 feet.

Vedanshi's map uses a coordinate plane. Match each location to its ordered pair.

• Park P

• (2, 4)

• House H

The rule is output = 3t + 11.

What is the output when t (input) = 3?

• 17

• 20

• 23

• 26

Answer explanation

To find the output when t = 3, use the formula: output = 3t + 11. Substituting t = 3 gives output = 3(3) + 11 = 9 + 11 = 20.

Using the rule output = 3t + 11, which output matches input t = 5?

• 23

• 24

• 25

• 26

Answer explanation

To find the output for t = 5, substitute 5 into the equation: output = 3(5) + 11 = 15 + 11 = 26. Therefore, the correct output is 26.

On a coordinate plane, which statement is true about graphing (1, 5) compared to (5, 1)?

• Both move 1 right then 5 up

• (1,5) is 1 right and 5 up

• (5,1) is 1 right and 5 up

• Both move 5 right then 1 up

Answer explanation

The point (1, 5) means you move 1 unit to the right (x-coordinate) and then 5 units up (y-coordinate). Thus, the correct statement is that (1, 5) is 1 right and 5 up.

Match each ordered pair to its movement from the origin.

• 1 right, 5 up

• (5,1)

• 0 right, 4 up

• (1,5)

• 5 right, 1 up

• (0,4)
