2x=12+2y How do I write this in slope intercept form?

Slope intercept form is y=mx + b where b is the y-coordinate.

2x = 12 + 2y subtract 2y from both sides

-2y + 2x = 12 subtract 2x from both sides

-2y = 12 - 2x arrange them in order of y=mx+b

-2y = - 2x + 12 divide both sides by - 2 (to reduce and have positive y value)

y = 1x - 6
