y = -4x + (8/3)
OpenStudy (anonymous):
you just divide the sides by 3
OpenStudy (anonymous):
so the slope is -4 @bballin629
OpenStudy (anonymous):
yeah I think so, not 100% sure but I'm pretty sure that, that's right
OpenStudy (anonymous):
ok

nope not -4
OpenStudy (anonymous):
sorry, a calculator usually helps with getting a slope so try that if you ever get stuck?
OpenStudy (anonymous):
-56
OpenStudy (anonymous):
the slope is definitely -4!
OpenStudy (anonymous):
it can't be -4

well actually yeah it has to be the more I think about it because y = mx + b
OpenStudy (anonymous):
would i put it as -4/1
OpenStudy (anonymous):
m in this case is -4, maybe it depends on the question that you're trying to answer?
OpenStudy (anonymous):
thats the same thing as -4...
OpenStudy (anonymous):
can you explain step by step

so you started out with 3y = -12x + 8 right?
OpenStudy (anonymous):
well in order to get y by itself, you would need to divide it by 3, and when you divide one side by 3, you have to do the same for the other side
OpenStudy (anonymous):
so after you're done dividing it would be y = -4x + (8/3)
OpenStudy (anonymous):
hope this helps?
OpenStudy (anonymous):
It is -4 ! the coefficient of "x" is always the slope!
