What is the distance between the points (−3, 5) and (−3, −9)? A) 4 B) 6 C) 11 D) 14

Distance formula is
D= square root of x2-x1 squared plus y2-y1 squared

for (-3,5) and (-3,-9) that would be

Square root of -3- - 3 squared plus -9-5 squared

This equals 14 which makes the answer D

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant

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.
