Answer:
Slope is -4
Step-by-step explanation:
You can use slope formula. To do this subtract the y's and put that on top of a fraction. (The y's are the second number in the parentheses).
8 - -4 is 12 (watch out for "minus a negative"; use your calculator if you're not sure) Put 12 on top of a fraction.
Then subtract the x's, put that on the bottom of the fraction. -1 - 2 is -3.
Slope is 12/-3. Then simplify it if you can.
slope = 12/-3 = -4.
You can also SEE the slope if you have a graph. Count how far up or down between the points,12, put that on top of the fraction. And count from left to right, 3, put it on the bottom.
The line is going down from left to right so be sure to write the slope is negative. You can see/check the line goes down4Over1, down4Over1, down4Over1, from one point to the other.
The slope is -4.
