The equation to graph by plotting 3 points is $y=0.5x-3$ This explanation will plug in -2,0, and 2 for x, but any 3 numbers can be used: $y=0.5(-2)-3$$=-4 y=0.5(0)-3$$=-3$ $y=0.5(2)-3$$=-2$ These three solutions provide an x and y-coordinate for each point. The numbers substituted for x will be the x-coordinates and the solutions to that will be the y-coordinates: $(−2,-4)$, $(0,−3)$, and $(2,−2)$.
