Which equation defines the line of best fit for the data in the table? x f(x)
-3 -2
0 -1
3 0
6 1
9 2

y=23x−1

y=13x−1

y=23x−10

y=13x−10

I would help but I don’t know how to do this question sorry

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.
