To find the x-intercept, simply plug in y=0 and solve for "x":


Ax%2BBy=C Start with the given equation.


Ax%2BB%280%29=C Plug in y=0


Ax%2B0=C Multiply


Ax=C Simplify


x=C%2FA Divide both sides by A to isolate "x".


So this means that when x=C%2FA, then y=0 which means that the x-intercept is

Note: A%3C%3E0
