an x intercept is a point on the graph where y=0

a y intercept is a point on a graph where x=0

To find the y intercept you first set x equal to 0, then solve for y.

2(0) - 4y=-8

-4y=-8.....divide both sides by -4

y=2.....the y intercept is 2.

Now to find the x intercept set y equal to 0, and solve for x.

2x-4(0)=-8

2x=-8......divide both sides by 2

x=-4.......the x intercept is -4.

To graph simply connect the dots of (-4,0) and (0,2)
