Question

Choose the point on the terminal side of -45°.
a. (-3, -3)
b. (4, -4)
c. (5, 5)
d. (-2, 2)

Answer 1

By convention, an angle starts horizontally on the right side of the x axis and opens counterclockwise. The negative means we will open clockwise. Since our angle is less than 90, and we're opening clockwise, we are in the fourth quadrant, where x values are positive and y values are negative. The only choice with a positive x but negative y is choice b. (4,-4)
