A-20.

Examine the graph at right. Then complete parts (a) and (b) below. A-20 HW eTool (Desmos). Homework Help ✎

In (

*x*,*y*) form, name the coordinates of points*A*,*B*,*C*, and*D*.Find the change in

*x*and*y*from the point (0,0).Point

*A*goes to the left 4 spaces and up 3 spaces.

How do you write that in (*x*,*y*) form?*A*is (−4,3). Now find points*B*,*C*, and*D*.On graph paper, draw a set of axes like the ones shown at right. Then plot points

*E*(5, 2),*F*(−3, −1),*G*(0, −4), and*H*(2, −3).

Remember that the horizontal axis is the

*x*-axis, and the vertical axis is the*y*-axis.
