Given that 6x = 7y, find the ratio x : y.

The only thing i can think would work is 6*7=7*6

42=42

7:6

reverse the numbers when given a ratio similar to this one. 6x7=42 and 7x6=42 so x is 6 y is 7

Hope this helps.

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.
