Question

What is the rectangular form of theta = 3pi/4?

Please answer this question if you 100% know this answer.

a. x - y = 0
b. x - y = 1
c. x + y = 0
d. x + y = 1

The answer was not a.

Answer 1

Answer:

  c.  x + y = 0

Step-by-step explanation:

The terminal ray of the angle θ = 3π/4 extends to the upper left through the 2nd quadrant with a slope of -1. It lies on the line ...

  y = -x

  x + y = 0 . . . . . . add x to get this standard form equation
