Can someone me?
i don't want the answer just someone to me through the problem.

2y+x=12
y=5/6x-2

First find out y, by dividing 5 to 6x, and then subtract 2 from that. Then, multip0ly y with 2 and subtract your answer with 12

You can also set both equations equal to y and then set them equal to each other or substitute the equation for y= in for the y in the other equation

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.
