Choose three numbers for x; I'll choose:  x = -2, x = 0, and x = 2

    x  |  y

---------

  -2  |                            Solve:  y  =  -2(-2) + 2  --->   y  =  4 + 2  --->  y  =  6

   0  |                            Solve:  y  =  -2(0) + 2  --->  y  =  2

   2  |                            Solve:  y  =  -2(2) + 2  --->  y  =  -4 + 2  --->  y  =  -2

Place these y-values into the table; plot the points, and draw the line.
