Answer:

m=-3/2

Explanation:

To find slope we can use the formula y2-y1/x2-x1

Let's plug in our points

-1-2/1--1 which is -3/2

Our slope is -3/2

Answer:

m=-3/2

Explanation:

In order to solve this problem, you must use the slope formula.

Slope formula:


\sf{(Y_2-Y_1)/(X_2-X_1)=(RISE)/(RUN) }

y2=(-1)

y1=2

x2=1

x1=(-1)

Rewrite the problem down.

Solve.


\sf{(-1-2)/(1-(-1))=(-1-2)/(1+1)=(-3)/(2)=\boxed{\sf{-(3)/(2) }} }

Therefore, the slope is -3/2, which is our answer.

I hope this helps you! Let me know if my answer is wrong or not.
