Let θ be the “angle of inclination” for the line through (x1,y1)as shown in the accompanying figure. For − π/2 < θ < π/2, tan θ is the slope of the line and the equation of the line is y − y1 = (tan θ)(x − x1). Find the equation in the form y = mx + b for each line described below.

The line through (−1, 2) with angle of inclination −π/4
