The endpoints of a line segment can be represented on a coordinate grid by the points A (-4, 1) and C (-4, -3). 

Graph and label each of the endpoints of the line segment on the coordinate grid below.

 The endpoints of a line segment can be represented on a coordinate grid by the points A (-4, 1) and C (-4, -3).

What is the distance, in units, between points A and C?

Peter wants to plot the point (2,3) on a coordinate plane.  Which statement describes how to plot this point starting at the origin?

• Move 2 units to the left and then 3 units down.

• Move 3 units to the left and then 2 units down.

• Move 2 units to the right and then 3 units up.

• Move 3 units to the right and then 2 units up.

A rectangle is graphed on a coordinate plane. The coordinates for two of the vertices of the rectangles are (-5,8) and (-5,-6). What is the distance between the two vertices?

      Which expression represents the distance between points A and B?

• |3| -  |-6|

• |4|  -  |-6|

• |-6| + |-4|

• |-6| + |3|

Point W is located at (-2, 3) on a coordinate plane.

Point W is reflected over the x-axis to create point P.
