    The slope-intercept form is called that because it shows you the slope. If
y = mx + b, then
the slope is m
the y-intercept is b
#2. If you rearrange the equation to read
y = (-4x+15)/3 = -4/3 x + 5
then you can just read off the intercept.
Note that the two lines are perpendicular, since the product of their slopes is -1.
