what is the slope of the line that passes through the points (1, -7) and (-2, -7)? write your answer in simplest form.
Answer
Explanation:
Step1: Recall slope formula
The slope formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Let $(x_1,y_1)=(1,-7)$ and $(x_2,y_2)=(-2,-7)$.
Step2: Substitute values
$m=\frac{-7-(-7)}{-2 - 1}=\frac{-7 + 7}{-2-1}$.
Step3: Simplify
$\frac{-7 + 7}{-2-1}=\frac{0}{-3}=0$.
Answer:
$0$
