Answer:
The number being multiplied by
x
is the slope of the line. So, the slope of the line is calculated by rise/run. The rise is how up or down it goes from a certain point to another, and the run is how right or left it goes from a certain point to the other.
So, the function is obviously shifted up by 1 so it rules out A and B, and we also see that the period is 4pi rather than 2pi, and using the fact that:

Now that we know our b value, we see that the correct answer would be C.
Answer:
Isolate "x" on one side of the algebraic equation by dividing the number that appears on the same side of the equation as part of "x." For example, in the equation "12x = 24", rewrite the equation as "x = 24 / 12" and solve for "x." The solution is "x = 2."

Answer:
start by putting in the y intercept, -4 on the y axis
then go up 5 and 1 right one to give your a slope of positive 5
