Answer:
im thinking n is 6.5 not sure wait not 6.5 its 3.5
I can't see what expressions you had posted. Maybe you didn't typed it out, but 649*36=23364
To answer this question, you need to subtitute a number for each n. First find the first and then push off of there.
slope is change in y over change in x
use 2 points from the table so -3,-21 and -6,-39
change in Y: -39 - -21 = -18
change in x = -6 - -3 = -3
slope = -18/-3 = 6
slope = 6
