Question

12x=4y+28

Answer 1

@Wingsofanangel help bro?

Answer 2

Is this for slopes?

Answer 3

12x=4y+28
12x-4y=28 <-- standard form

-4y=-12x+28
-(-4y=-12x+28)
4y=12x-28
(4y=12x-28)/4
y=3x-7
m=3 b=-7 <---y=mx+b form

Answer 4

oops, he beat me to it xD

Answer 5

their is no m or b its solving for y @Wingsofanangel

Answer 6

then y=3x-7

Answer 7

are you sure? @Wingsofanangel

Answer 8

y=3x-7
if you're finding the y-intercept only.solve for x first
so the solution will be:
let the y=0 first so you can solve for x
y=3x-7
0=3x-7
-3x=-7
(-3x=-7)/-3
x=7/3


then you can solve for the y next.
just substitute 7/3 to x
y=3x-7
y=3(7/3)-7
y=7-7
y=0
