Slope: 0
Step-by-step explanation:
(-3,5) (4,5)
y2-y1/x2-x1
5-5/4+3=0/7
0/7 simplifies to 0.
So the slope of the line (-3,5) (4,5) is 0.
Hope this helps! ;)

Answer:
E. (The function is exponetial)
Step-by-step explanation:
We look at the output values and subtract them from their previous value to see it's slope.
6-2 = 4
12-6 = 6
4 ≠ 6, meaning that the slope is not constant.
4 < 6, meaning that the slope is increasing, meaning the function is exponential.
