Slope of the line passing through the given pair of points?

Question

(-6,-12) and (-18,-24)

Answer 1

The points are (-6, -12) and (-18, -24).

Substitute (x₁, y₁) = (-6, -12) and (x₂, y₂) = (-18, -24) in the slope formula: m = (y₂ - y₂)/(x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are two points.

m = [-24 - (-12)] / [- 18 - (-6)]

m = (-24 + 12) / (- 18 + 6)

m = (-12) / (-12)

m = 1.

The slope of line is 1.
