A-20.

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

  1. 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.

  2. 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.
