**Henry**, Tuesday, August 6, 2013 at 7:21pmThe angle of inclination is always between 0o and 180o and is measured CCW from the positive x-axis.

A. x+y+1 = 0

x+y = -1

Tan A = m = -A/B = -1/1 = -1

Ar = -45o = Reference angle.

A = -45 + 180 = 135o.

B. 3-2y = 9x

9x+2y = 3

Tan A = m = -A/B = -9/2 = -4.5

Ar = -77.47o

A = -77.47+180 = 102.5o
