Question

A line has a slope of 1 and passes through the point (7,5). What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answer 1

Answer:

$y=x-2$

Step-by-step explanation:

Slope-intercept form is $y=mx+b$, so if $m=1$, then we have $y=x+b$ and we'll need to plug in $(7,5)$ to get $b$, the y-intercept:

$y=x+b$

$5=7+b$

$-2=b$

Therefore, the final equation in slope-intercept form is $y=x-2$
