Question

Write an equation in point-slope form of the line that passes through the point (3, -4) with slope 1.

Answer 1

y=x-7

Explanation:

1) First, plug in 3 as x, -4 as y, and 1 as m to y=mx+b, you now have -4=1(3)+b

2) subtract 3 from both sides to get-7 on the other side and you have just solved for b in your equation.

3) enjoy the answer.
