slope intercept form means y=mx+n m is the slope n the yintercept n=3 you still need m you know that if 2 lines are perpendicular ,the product of their slopes is 1 first thing now is to determine the slope of 3x2y=9

i get 2y=3/2x9/2 correct

then my final answer should be y=3/2x3 correct

if you have 2y=3x+9 then divide all by 2 you get either y=(3/2)x+(9/2) or you can factor to 3(x3)/2 \[\frac{ 3(x3)}{ 2}\] I prefer the first one which would look like \[\frac{ 3 }{ 2 }x+\frac{ 9 }{ 2 }\]

yeah so it should be (3x+9)/2 which is \[\frac{ 3 }{ 2 }x\frac{ 9 }{ 2 }\]

okay and the final answer should be y=3/2x3 or y=2/3x3?

sorry trying to do one of mine. yes y=2/3x3

because your perpendicular line is a negative reciprocal of the original one so the original was (3/2) and the negative reciprocal is (2/3)

and they give you the y intercept of 3 or b
