Answer:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
Subtract 6 on both sides


Multiply -2 on both sides to get "x" by itself

x = -8
C ÷ D- EXPRESSION
-24÷1/4=-18
24
- 6
---------
18
The answer is negative because when you divide 24 by 4 you get 6. and since the number 24 is negative.you need to subtract 6 from 24 to get -18 which is negative.
P.S:I am a 6th graders who doesn't really understand negatives, but i tried my best and got this answer.
