Question

A line includes the points (5, 3) and (8,9). What is its equation in slope-intercept form?

Write your answer using integers, proper fractions, and improper fractions in simplest form.

y =_ x- _

Answer 1

y=2x-7

Explanation:

y=mx+b

Slope (m)=
`(9-3)/(8-5) =(6)/(3) =2`

Y-Intercept (b)=
`y=2x+b\\3=10+b\\b=-7`
