Question

Which line L has a slope of zero?

Answer 1

I think D because
It is horizontal and therefore the slope is zero

Answer 2

D

Explanation:

Gradient

A Gradient is also called a slope of a line, which represents how steep a line is.

Formula of slope: Vertical difference ÷ Horizontal difference

For a slope to be zero, the line must be horizontal.

Solution

Based on the question given, we can deduce that D is a horizontal line and therefore the slope is zero.
