Answer is A. m= -1/5
Step by step
To find slope, (y2-y1) over (x2-x1)
(-5)-(-4) over 3-(-2)
-1 over 5
m = -1/5

\large\boxed{\textsf{A.}\ m=-(1)/(5)}

We can use the slope formula, where our points are
(x_1,y_1) and
(x_2,y_2):


(y_2-y_1)/(x_2-x_1)

This is also known as "rise over run" because it represents the change in vertical (
y) position divided by the change in horizontal (
x) position.

Substitute the values from the points given:


((-5)-(-4))/(3-(-2))

Subtract:


\boxed{(-1)/(5)}
