Question

Consider this system of equations. Which shows the first equation written in slope-intercept form?

1/2 (2y + 10) = 7x
y=8

Answer 1

You're correct it's
`y=7x-5`

Explanation:

If you isolate y that's the correct answer.

`1/2(2y+10)=7x`

Just multiply the things in the parenthesis by 1/2:

`y+5=7x`

Then isolate y further by subtracting five from each side to get the answer:

`y=7x-5`
