help!!!!!

OpenStudy (ageta):

Write the following linear equations in slope-intercept form

OpenStudy (ageta):

2x-4y=12

OpenStudy (solomonzelman):

\(\large\color{slate}{ \displaystyle y=mx+b}\) is the slope intercept form.

OpenStudy (solomonzelman):

you need to rearrange it. Solve for y.

OpenStudy (ageta):

go on

OpenStudy (solomonzelman):

\(\large\color{slate}{ \displaystyle 2x-4y=12}\) you need to isolate the y. 1. subtract 2x from sides 2. divide each term in the equation by -4. if you do it correctly, you are done.

OpenStudy (anonymous):

correct ^^^ :), so what would you get

OpenStudy (ageta):

y=-2/4x+3

OpenStudy (solomonzelman):

close

OpenStudy (solomonzelman):

\(\large\color{slate}{ \displaystyle -4y=-2x+12}\) is what you get when you subtract x from both sides. when you divide each term by -4, \(\large\color{slate}{ \displaystyle \frac{-4y}{-4}= \frac{-2x}{-4}+ \frac{12}{-4}}\)

OpenStudy (solomonzelman):

please try one more time... (you got the numbers, but made some mistakes on signs)

OpenStudy (ageta):

y=2/4x +8

OpenStudy (ageta):

is this right

OpenStudy (solomonzelman):

12/(-4) = -3

OpenStudy (solomonzelman):

\(\large\color{slate}{ \displaystyle y=\frac{2}{4}x-3 }\) and then one more thing you can do....

OpenStudy (ageta):

oh.. i got it now

OpenStudy (ageta):

tnxs

OpenStudy (solomonzelman):

you can reduce the 2/4

OpenStudy (solomonzelman):

2 and 4 can both be divided by 2

OpenStudy (ageta):

1/2

OpenStudy (solomonzelman):

Yes, \(\large\color{slate}{ \displaystyle y=\frac{1}{2}x-3 }\) !

OpenStudy (anonymous):

correct @ageta @SolomonZelman

OpenStudy (solomonzelman):

tnx lol

OpenStudy (anonymous):

lol i was a little to late but you seem smart so... :D
