y = -6x - 2y = -6x-2
y = 0.5x+5, y = 0.5x + 1
y = 0.25% -2, y = 5x - 4
y = 2x + 3, y = 4x-1
y = 2x + 1.5, y = 2x + 1.5
y=-x-3, y = -x + 3

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.
