**Damon**, Tuesday, February 1, 2011 at 10:10amdy/dx = 7 - 4x

at (-1,-9)

dy/dx = m = 7 - 4(-1) = 11

plug in point

-9 = 11 (-1) + b

-9 = -11 + b

b = 2

**drwls**, Tuesday, February 1, 2011 at 10:12amFor the slope, calculate df/dx at x = -1.

m = df/dx = 7 - 14x = 21

y = 21x + b

-9 = -21 + b

b = 12

y = 21x +12
