Question

What is the slope of the line that passes through (2, 5) and (–1, 5)?

Answer 1

The slope of a line through `(2,5)` and `(-1,5)` is 0

Explanation:

Since the value of `y` is a constant, the "change in y" is `0`
and the slope, which is defined as the "change in y" divided by the "change in x", is equal to zero.
