points that two lines pass through are given in the table.
match each point of intersection to the correct pair of
lines. (1, 1) (1, -1) (-4, -7) (-5, -4) (4, 7) (-4,-5)

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.

Ithink your answer is b
