Plotting is the place the dots belong to?
If you want to do a positive of which is like (x,5) then you go to in between the right top and bottom or x axis where the positives are and count, if the (2,y) is positive you count and go up if y is a negative then you count down how many number there is.
Let’s use (1,-1) first you go into the x-axis, one is a positive so you go to one in there, and go down one or to -1 bc the -1 is a negative and the digit is 1. ( I hope it made sense, if u need more help u can tell me.)

Answer:
k = 3.70
Step-by-step explanation:
Eliminate parentheses, then subtract the constant term on the left
8.5 +4 -10k = -24.5

k = 3.70 . . . . . . . . . . . both sides divided by -10 (no rounding required)
