----------------------------------------
To find ANY y-intercept, let x=0.
You get:
y = (-5)(3)(-2) = 30

------------------
The y-intercept is the point at x = 0.
If you multiply the 3 binomials, the constant will be 30 (-5 x 3 x -2).
Setting x = 0 will make all the other terms 0, and you're left with the 30.
The y-intercept is (0,30)
