see explanation.

Explanation:

To obtain 3 points, choose any values of x and substitute into the equation for corresponding values of y.

•x=0toy=0+2=2rArr(0,2)

•x=2toy=-2+2=0rArr(2,0)

•x=-3toy=-(-3)+2=5rArr(-3,5)

Plot the 3 points (0 ,2) , (2 ,0) and (-3 ,5) and draw a straight line through them. You then have the graph of the given equation.
