The equation of a line with slope and given point. m=-4, (4,8)is
y-y1 = m(x-x1)
y-8 = -4(x-4)
y-8 = -4x+16
4x+y = 24

y = mx+b
y = -4x + b
.
We're told one point on the line: (4,8)
So, when x=4, y = 8
Substituting,
8 = -4(4) + b
8 = -16 + b
24 = b
b = 24
.
y = -4x + 24
.
x = 0, y = 24
x = 6, y = 0
.
