Write these in slope form 1. 5x + 4y = 20
2. 4x + 14y = 28
3. 12x – 9y = 45
4. -5x + 15y = -60
5. 3y + 2x = -15

wht is the slope & y-intercept fo these?

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.
