Question

Find the slope of a line parallel to 3x – y = 1.

A. –3
B. 3
C. one third
D. negative one third

Answer 1

m =3

Explanation:

3x – y = 1

First put the line in slope intercept form

y = mx+b where m is the slope and b is the y intercept

-y = -3x+1

y = 3x-1

The slope is 3

We want a line parallel, which means the lines have the same slope

m =3
