On a coordinate plane, line A B goes through (negative 2, 4) and (2, negative 8). Point C is at (6, 4). Which point on the y-axis lies on the line that passes through point C and is perpendicular to line AB?

(–6, 0)
(0, –6)
(0, 2)
(2, 0)

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.

The answer is b: step 2.
