2-21.

Examine the graph below.  2-21 HW eTool (Desmos).  Homework Help ✎  

2-20graph

  1. Name the coordinates of points A, B, C, and D in (x, y) form.

    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. Draw a set of axes like the ones shown at right on graph paper.  Then plot points E(5, 2), F(–3, –1), G(0, –4), and H(2, –3).  

    Use the points above and the graph above to plot points E, F, G, and H. Remember that the horizontal axis is the x-axis, and the vertical axis is the y-axis.

Use the eTool below to input the points into the table and graph the results.
