  1. Set x = 0 and solve for y.
    Set y=0 and solve for x.

  2. another way is...
    you can substitute the x and try to solve for y.
    what can 5 go to?
    5,10,15,20...
    so if x=2 then the equation will be
    6-5y=25
    however -5y cant go to 19
    so try another number
    at the end, you will have x=5
    there, 15-5y=25
    -5y=10
    y=-2
    i hope you understand the idea of it
