3x-4y=12 how do I turn it into slope intercept form

Question

what r the step to make it into a slope intercept.

Answer 1

You want it in the form

 

y = mx + b

 

3x - 4y = 12

 

Solve for y in terms of x.

 

-4y = 12 - 3x

 

y = (12/-4) - (3x/-4) = -3 + 3x/4

 

y = (3/4)x - 3

Answer 2

So, you need y by itself. We do this by doing opposite operations.

 

3x - 4y - 3x = -3x - 12

-4y = -3x - 12

-4y/-4 = -3x/-4 - 12/-4

y = (3/4)x + 3
