Answer:

A, C, E, F

Step-by-step explanation:

Functions mean that each x-value can only go to one y-value, but the same x-value can't go to 2 different y-values.

Different x-values, such as x=-4 or x=5, CAN go to the same y-value as shown in C.

But for B, x=5 can't go to both y=0 and y=8

Slope (12,-18),(11,12)

olga nikolaevna [1]

If you are trying to find the slope using only these two points then you should first take note of what your X and Y values are. For instance, 12 & 11 are your X values and -18 & 12 are your Y values. Knowing this you can now find your slope by doing y2-y1/
x2-x1. You will get the fraction -30/1 or -30 which is your slope. Hope that made sense!
