Question 1

Which statements about the coordinate grid are true? Select TWO correct answers.

Accepted Answer

The intersection of the x-axis and the y-axis is called the origin and is represented by the ordered pair (0, 0).

Accepted Answer

When graphing in a coordinate grid, the first number in the ordered pair represents the parallel movement on the x-axis, starting at the origin and moving right.

Answer

In a coordinate grid, the x-axis and the y-axis are parallel to each other.

Answer

The horizontal number line is called the y-axis, and the vertical number line is called the x-axis.

Answer

When graphing in a coordinate grid, the first number in the ordered pair represents the parallel movement on the y-axis, starting at the origin and moving up.

Question 3

Lisa drew four points on a coordinate grid. One of the points represents the origin of the coordinate grid. Which ordered pair did Lisa draw at the origin of the coordinate grid?

Accepted Answer

(0, 0), because the origin is located at the intersecting point of the x-axis and y-axis where the x-coordinate and y-coordinate are both zero.

Answer

10, 10, because the origin is located at an intersecting point where the x-coordinate and y-coordinate are the same.

Answer

10, 0, because the origin is located at a point on the y-axis with a y-coordinate of zero.

Answer

0, 10, because the origin is located at a point on the x-axis with an x-coordinate of zero.

Question 4

Emily is playing a game with a game board designed like a coordinate grid. The ordered pair (0, 4) represents the point where her game piece is located on the grid. In this ordered pair, what does the number 4 indicate?

Answer

The number 4 indicates movement of 4 units up parallel to the x-axis starting at the origin.

Answer

The number 4 indicates movement of 4 units to the right parallel to the x-axis starting at the origin.

Answer

The number 4 indicates movement of 4 units to the right parallel to the y-axis starting at the origin.

Question 5

Frank drew a coordinate grid over the top of his map so he could reference different towns on the map. The ordered pair (18, 0) represents the point on the map where his hometown is located. In this ordered pair, what does the number 18 indicate?

Accepted Answer

The point is 18 units to the right of the origin on the x-axis.

Answer

The point is 18 units above the origin on the y-axis.

Answer

The point is 18 units to the right of the origin on the y-axis.

Answer

The point is 18 units above the origin on the x-axis.
