Question

what is the slope of this line?
(-5, -1) (-3, -1)
options: 2, -2, 0, undefined

Explanation:

Step1: Recall slope formula

The slope \( m \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is given by \( m=\frac{y_2 - y_1}{x_2 - x_1} \).

Step2: Identify the two points

We have the points \((-5, -1)\) and \((-3, -1)\). Let \((x_1, y_1)=(-5, -1)\) and \((x_2, y_2)=(-3, -1)\).

Step3: Substitute into the formula

\( m=\frac{-1 - (-1)}{-3 - (-5)}=\frac{-1 + 1}{-3 + 5}=\frac{0}{2}=0 \).
