If you're referring to standard linear form Ax+By = C, then pick any integer values you want for A and B such that they arent equal to 1. Pick anything you want for C.
For instance: A = 14, B = 7, C = 28
Ax+By = C
14x+7y = 28
--------------
If you want to solve for y, then
14x+7y = 28
7y = -14x+28
y = (-14x+28)/7
y = (-14/7)x+28/7
y = -2x+4
which is now in slope intercept form y = mx+b with m = -2 as the slope and b = 4 as the y intercept.
