  1. y= mx + b

    there is no b so b = 0
    You will start your graph at (0,0)

    m = -1.5 means that the graph will slant downward from left to right
    -1.5 = -3/2 or 3/-2

    you can move down -3 and to the right 2

    or up 3 and to the left 2 to start your graph. Follow this pattern.

    x has to = 2 when y = -3.

    dived the y values given by -1.5 to find the other x values.
