Need fast ! what is the slope of this line? the line passes through theses coordinates (-2, -2, -8)

Ok, so now that I reread this question, I can give you that answer.

First, graph a line of which passes through -2,-2, and -8. I believe they can be either x or y coordinates If not, plz correct me. This will give you a line that goes down as shown in the picture. Now what you do is that you count how many times up it takes you to get to the next plot and how many times you go left. Your slope will come out to be -4

What is the number for e if you don't knkw then there is no answer you need that number to plug in then multiply that number with 5.9 then add 10
