When finding the x-intercept you replace y by zero and solve for x. In your equation, you first need to set the equation in the form of slope intercept y=mx+b so x can be easier to solve for.

no you don't 
just erase the $y$ and get $x=20$

anonymous · Answer

n order to find the x-intercept, you must substitute the y as 0, as any x-intercept has a y-value of 0. 
Therefore... 
x - 4y = 20 
x - 4(0) = 20 
x = 20 

The x-intercept is 20.
