    To get x-intercept put y=0 in the equation to get y-intercept put x=0 in the equation

    1.) 4y-8=2x Add 8 4y = 8 + 2x Subtract 2x 4y - 2x = 8 Divide by 8 \[\frac{y}{2} + \frac{x}{-4} = 1\] This is called the "Intercept Form". The answers are staring at you.

    -8=2x so x= -8/2 = ?

    Now go take a look at that Intercept Form and see if anything looks interesting - particularly the denominators.
