Answer:
Step-by-step explanation:
(5,-4) (4,0)
y2 = 0, y1 = -4, x2 = 4, x1 = 5
Slope m = (y2 - y1)/(x2 - x1)
m = (0 + 4)/(4 - 5)
m = 4/-1
Slope m = -4
And the equation is
y - y1 = m(x - x1)
y + 4 = -4(x - 5)
y + 4 = -4x + 20
y = -4x + 20 - 4
y = -4 + 16
That is the equation of line
So comparing with y = mx + c
C = y intercept = 16
