What is the graph of the equation 4x – 5y = 15?

4x - 5y = 15
put x=0, 4(0) - 5y = 15
               -5y = 15
               y = -3
coordinates (0,-3)
put y=0, 4x - 5(0) = 15
              x = 15/4
coordinates (15/4,0)
put y=1, 4x - 5(1) =15
              4x = 20
              x = 5
coordinates (5,1)

Plot the three coordinates to obtain a straight line.
Note: You can also use other points rather from what i mentioned.

Hope it helped!
