What is the slope of a line that is perpendicular to the line x=-3?

a(-3
b(0
c(1/3
d(underfined

Perpendicular = Negative Reciprocal

-3 --> -1/3 ---> 1/3

Therefore it is C

C-1/3 because the slope of a line that is perpendicular to another line is the negative reciprocal of the original slope. 

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.
