Question

Which is an equation of the line that passes through (–1, –5) and (–3, –7)?

Question 8 options:

a)

y = x – 4


b)

y = –2x + 4


c)

y = 2x + 4


d)

y = –x – 4

Answer 1

a) y = x - 4

First, to find the rate of change [slope], do rise\run: -y₁ + y₂\-x₁ + x₂. Doing this will result in the slope being 1, and the ONLY answer that has a slope of 1, is the top choice.

Slope-Intercept Formula: y = mx + b [m represents slope].
