Question

Write 10x - 5y = -30 in slopeintercept form.
y =
X +

Answer 1

Answer: y=2x+6

Explanation:

A slope-intercept form is y=mx+b

Hence,

`10x-5y=-30\\\\10x-5y+5y=-30+5y\\\\10x=-30+5y\\\\10x+30=-30+5y+30\\\\10x+30=5y`

Divide both parts of the equation by 5:

2x+6=y

Thus, y=2x+6

Answer 2

`y=2x+6`

Explanation:

Slope-intercept form is
`y=mx+b`.

Therefore, rearranging the given formula:

`10x-5y=-30`

`-5y=-10x-30`

`(-5y)/(-5)=(-10x)/(-5)-(30)/(-5)`

`y=2x-(-6)`

`y=2x+6`
