Slope-intercept form: y = -2x - 1. Convert this to point-slope form:
Find a point on the graph. It's (0, -1), since y = -2(0) - 1 = -1.
Then the point-slope form is
y-(-1) = -2(x - 0)
The sum of the angles of a quadrilateral is 360°.

Given that x=30, the measure of ∠C is
∠C = (5/2)×30 +40 = 115
The appropriate choice is ...
D) 115°
