Question

Which of the following best describes the slope of the line below?

A: negative
B: zero
C: undefined
D: positive

Answer 1

B. zero

Explanation:

Lines with negative slopes slant downward from left to right

Lines with positive slopes slant upward from left to right.

Lines with undefined slopes are vertical lines.

Lines with zero slopes are horizontal lines.

This is a horizontal line, so it must have a slope of zero. This is because it is a horizontal line, and the y-coordinate never changes.
