Question

How do you find the slope of a line parallel to `3x-y=1`?

Answer 1

`3`

Explanation:

If 2 lines are parallel, it means that their slopes are same.
`y_1=color(red)mx_1+b_1`
`y_2=color(red)mx_2+b_2`

`color(red)m` is the slope and it has to be same in each line. So in this equation, we have to convert to `y=mx+b`.
`3x-y=1`
`y=3x-1`
As we see `color(red)m` or the slope is `3`.
