2 points Find the value of y that that is required to show that PQRS is a
parallelogram. You will need to use a system of equations to solve this
problem. Depending on how you set up your system of equations, you
might even need to solve for x before you solve for y.

3x + 2y
4x + y

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.

Set up a system of equations
