Hello!

Explanation:

Slope formula: →
(Y^2-Y^1)/(X^2-X^1)


(3.1-6.1=-3)/(-2.5-(-5.5)=-2.5+5.5=3)=(-3)/(3)=-1

So therefore, the slope is -1.

Answer is -1.

*The answer must have a negative sign.*

Have a great day! :)

Thank you!

The answer is A because slope is equal to the change in y over the change in x. Substitute in the values of x and y into the equation to find the slope.m=3.1−(6.1)/−2.5−(−5.5)
