Question

Help!!!!
write the slope intercept form of the equation of each line.
3x - y = 4

Answer 1

Slope-intercept form looks like this:\[\Huge y = mx+b\]It's like all you have to do is isolate y. Do you know how to?

Answer 2

i don't know how to isolate y :( that's the part i get stuck at

Answer 3

ok, 3x is with y, and we don't want this, so subtract both sides by 3x to isolate y.

Answer 4

Now we have -y = 4 - 3x. You know what to do next?

Answer 5

dont you divide -y to all sides?

Answer 6

It's isn't good idea because if you do this, you unisolate y.\[\Large -y = 4 - 3x\]
\[\Large \frac{-y}{-y} = \frac{4-3x}{-y}\]
\[\Large 1= \frac{4-3x}{-y}\]

Answer 7

We want to isolate y. We have to deal with negative sign. Do you know how to get rid of it?

Answer 8

no :(

Answer 9

-y is same as (-1)( y )

Does this help?
