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

By definition, the slope or gradient of a line describes its steepness, incline, or grade.

Slope (m) = ΔY/ΔX= 0

ΔX = 2 – 1 = 1

ΔY = -7 – -7 = 0

Equation of the line:

y = 0x – 7

When x=0, y = -7
