Let m = slope

m = (-3 -(-1))/(-4-(-2))

m = (-3 + 1)/(-4 + 2)

m = -2/-2

m = 1

Use the slope, one of the points given and the point-slope formula to find your equation.

Answer:

The slope is 1.

Step-by-step explanation:

SLOPE FORMULA:

[tex]\longrightarrow \displaystyle \mathsf{\frac{y_2-y_1}{x_2-x_1}=\frac{rise}{run}  }[/tex]

Y₂=(-3)

Y₁=(-1)

X₂=(-4)

X₁=(-2)

Solve.

[tex]\displaystyle \mathsf{\frac{(-3)-(-1)}{(-4)-(-2)}=\frac{-2}{-2}=\boxed{\mathsf{1}}  }[/tex]

As a result, the slope is 1, which is our answer.
