Question

Write an equation of the line passing through (-3,2) and is parallel to the line x-y = 7?

Answer 1

Try subbing (-3,2) as (x,y) in the formula y=mx+c.

Answer 2

First find slope
x-y=7
-y=-x+7
y=x-7
Slope is 1
use the equation
\[y-y _{1}=m(x-x_{1})\]
y-2=1(x+3)
y-2=x+3
y=x+5

Answer 3

Or -x+y=-5
