Question

A line passes through the points (6,9) and (8,10). 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 = (10 − 9)/(8 − 6) = 1/2. Using point (6, 9):

y − 9 = (1/2)(x − 6).
