y intercept means x = 0. So plug that in to get 0 - 4y = 15.
y = 15/(-4)
So: -15/4 or -3.75

Slope intercept-formula
y = mx + b
5x-4y=15
-4y = 15 - 5x
4y = 5x - 15
y = (5/4)x - 15/4
slope = 5/4
y intercept = -15/4
.

y= 5/4x-15/4
the y intercept would be -15/4

subtract 5x from both sides. Therefore, you have -4y=-5x+15. Divide both sides by -4. You get your y value. =)

Solve by plugging in zero for x.
You need to do your own homework.
