What is the slope of the line? a. -2 b. -1/2 c. 1/2 d. 2

The slope of the line is "-1/2" which is answer B.

B. -1/2

because the slope is the rise over the run. The rise is -1 and the run is 2.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
