How do i write the slope (which i found using y2-y1/x2-x2) in slope intercept form (y=mx+b)?

In y = mx + b, m is the slope and b is the y-intercept.

So, first substitute the value: your found slope goes in the place of m

Then, find the y-intercept by, in addition to substituting your slope, replace x with the x value of your coordinate and y with the y value of your coordinate in the formula and solve for b

Hope this helps!

What can we do about it

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.
