Answer:
2.4 or 12/5
Explanation:
The slope formula is (y2-y1) divided by (x2-x1).
First, you label each number by their x and y.
-4 will be axis x 1
2 will be axis y 1
-9 will be axis x 2
-10 will be axis y 2.
Then substitute the variable into the formula.
(-10 subtract 2) divided by (-9-(-4)).
Next, solve. Once you solve you will get -12/-5 = 2.4
Finally, simplify the answer. if it is already simplify, that will be the answer.
