Question

I don’t understand can somebody help me

Answer 1

y=(4/11)x+(-7/11)

`y=(4)/(11)x+(-7)/(11)`

Explanation:

Slope-intercept form is y=mx+b.

So we need to solve 4x-11y=7 for y.

First step: Get term that contains y by itself. The term that contains y is -11y.

We need to subtract 4x on both sides:

4x-11y=7

-4x -4x

---------------------

0-11y=7-4x

-11y=7-4x

-11y=-4x+7 (Addition is commutative)

Divide both sides by -11:

y=(-4/-11)x+(7/-11)

Negative/negative is positive while positive/negative is negative.

So we have:

y=(4/11)x+(-7/11)
