is anybody good at calulus and has time to help me???????????

OpenStudy (anonymous):

im ok what is up

OpenStudy (anonymous):

@kaylalynn can you help me real quick and then i am willing to help you Identify the correct x intercept and y intercept of the equation 2x - 3y = -18. x intercept = (9, 0); y intercept = (0, -6) x intercept = (6, 0); y intercept = (0, -9) x intercept = (-9, 0); y intercept = (0, 6) x intercept = (-6, 0); y intercept = (0, 9)

OpenStudy (anonymous):

you there @kaylalynn

OpenStudy (anonymous):

Rearrange that equation into the usual y=mx+b form

OpenStudy (anonymous):

Whatever b ends up being is your y intercept.

OpenStudy (anonymous):

so what would it be because i dont know how to do it

OpenStudy (anonymous):

Give it a shot first. Just try to isolate y on one side. Your first step would be to subtract both sides by 2x.

OpenStudy (anonymous):

so it would be B

OpenStudy (anonymous):

Lets see. 2x-3y=-18......-3y=-18-2x......y=-18/-3-2x/-3....Work at it from there.

OpenStudy (anonymous):

that makes me confused

OpenStudy (anonymous):

\[y=\frac{ -18 }{ -3 }-\frac{ -2x }{ -3 }\]

OpenStudy (anonymous):

Is that better?

OpenStudy (anonymous):

yes thank you

OpenStudy (anonymous):

Simplify and try to get it to look more like y=mx+b. m Is your slope by the way.

OpenStudy (anonymous):

|dw:1387503930371:dw| is this how you would do this
