Answer:

Step-by-step explanation:
We start off with 3.2n + 13.3 = 26.1.
We need to get n by itself.
Subtract 13.3 from both sides.


We end up with: 
Divide 3.2 on both sides to get n by itself.

The slope is 7/8.
Slope formula is the change in y over the change in x,
M=y2-y1 / x2-x1
M= -3 - (-10) / -2 - (-10)
Remember that two negatives equal a positive.
That makes the equation:
M= -3 + 10 / -2 + 10
M= 7/8
