Unit 9 Review

Dr. Cantu is a physical therapist who has the same number of appointments available for patients each day. The relationship between x, the number of days she works, and y, the number of appointments she has available, can be represented by the equation y = 14x. Create a table that represents the equation y = 14x.

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

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

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

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

• 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.

• 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.

Marco made a map on a coordinate grid. He graphed the point (7, 6) to show the beginning of his favorite hiking trail. Which statement describes the process he used to graph the point on the coordinate grid?

• Marco graphed the point 7 units to the right of the origin along the x-axis and 6 units up parallel to the y-axis.

• Marco graphed the point 6 units to the right of the origin along the x-axis and 7 units up parallel to the y-axis.

• Marco graphed the point 7 units above the origin along the y-axis and 6 units to the right parallel to the x-axis.

• Marco graphed the point 6 units above the origin along the y-axis and 7 units to the right parallel to the x-axis.

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?

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

• (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.

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

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

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?

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

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

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

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

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?

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

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

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

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