21 its 21 because it is 21
Slope y-intercept form is: y=mx+b
All you have to do is rearrange the equation:
2x-3y=6
2x=6+3y
2x-6=3y
now divide both sides by 3
(2x/3)-(6/3)=(3y/3)
and it becomes

x
Bonus: you can plug in any two values for x and y and you can see both equation gives the same answer!
I'm OKAY at it, depends on the question
The correct answer is 0,10
The answer is always negative because if you multiply like signs, the answer is positive, unlike signs are always negative
