Question

How do you answer this? (this is for slopes.)

Answer 1

`y= 2x + 4`

Explanation:

We are given an equation of
`2x-y+3 =-1` and we need to put into
`y = mx+b` form.

First, we subtract 3 on both sides to get the variables all on one side.

`2x-y+(3 - 3)=(-1 -3)\\\\`

`2x-y = -4`

We need to now isolate y on its own so we subtract
`2x` on both sides.

`(2x-2x)-y=(-4-2x)`

`-y=-2x-4`

We almost done! We then need to divide the invisible negative on both sides which is a -1.

`(-y)/(-1)=(-2x-4)/(-1)`

`y=2x+4`

When we divide the the negatives together, we know that two negatives divided together is a positive. Therefore, we get our answer
`y=2x+4`

Hoped this helped!
