Question

A line passes through the points (–5,–7) and (–7,–3). What is its equation in point-slope form?
Use one of the specified points in your equation. Write your answer using integers, proper fractions, and improper fractions. Simplify all fractions.

Answer 1

Slope m = (-3 - (-7))/(-7 - (-5)) = 4/(-2) = -2.
Using point (−5, −7): y - (−7) = -2(x - (−5)) so
y + 7 = -2(x + 5).
