Question

What is the slope of the line that passes through the points (1,-7) and (-2,-7)? Write your answer in simplest form.

Answer 1

The slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the formula \[\frac{y_2 - y_1}{x_2 - x_1}.\] In this case, $(x_1,y_1) = (1,-7)$ and $(x_2,y_2) = (-2,-7),$ so the slope of the line is \[\frac{-7 - (-7)}{-2 - 1} = \boxed{0}.\]
