2x + 4y=8
4y=8-2x
y=-2x + 8
y=-(2/4)x + (8/4)
y=-(1/2)x + 2
y-intercept: is 2
(0,2)

x=0
2x+4y=8
2(0)+4y=8
0+4y=8
4y=8
y=2
y intercept is (0,2)
Whenever they ask you for an intercept, plug in 0 for the other value. So, if they ask for the x intercept...you plug in 0 for y and if they ask you for the y intercept...you do what i did above which is plug in 0 for x. Not too hard huh?

You want you equation in slope-intercept form: y = mx + b
Solve it for y as in the previous equation you posted.
An alternate way is substitute 0 for x and solve for y. A y-intercept always has 0 for the x coordinate.
