To graph this equation easily, select three arbitrary values of x. For example, x= 0, x= 2 and x= - 3

To find the y values , substitute each x value in the equation.

For example, when x=2, y= 5 x 2 + 3 =13 so one pair is ( 2, 13 )

Other pairs are ( 0, 3) and (-3, -12)

Now you have three pairs. Locate these three points ( pairs) in x-y plane. Connect these points and you have the required straight line graph of the equation y = 5x +3
