mathslover (mathslover):
first put x = 0 in the equation to find y intercept :
-6(0)-3y=27
solve for y, what do you get?
OpenStudy (anonymous):
x=9? This is so confusing
mathslover (mathslover):
what is -6 * 0 ?
OpenStudy (anonymous):
0
mathslover (mathslover):
right now:
-6*0 -3y = 27
-3y =27 right?

yes
mathslover (mathslover):
now can u solve for y?

Oh sorry man.......I'll remove it.
OpenStudy (anonymous):
I'm sorry, I just don't get it.

-3y = 27
divide both sides by -3 and then try to solve
OpenStudy (anonymous):
y=-3
OpenStudy (anonymous):
no, y = -9
mathslover (mathslover):
y = - 9 correct
mathslover (mathslover):
now put y = 0 that is solve for x:
-6x+3(0) =27

is it not supposed to be -6x - 3(0)=27?
mathslover (mathslover):
oh yes sorry - is there
so solve for x : -6x = 27
OpenStudy (anonymous):
-6x - 3(0) = 27-6x=27?
mathslover (mathslover):
yes..
since -3*0 = 0
hence -6x-3*0=27
-6x=27
OpenStudy (anonymous):
ok so do i divided both sides by -6x?

mathslover (mathslover):
no no divide both sides by -6
OpenStudy (anonymous):
this part is confusing, what am i missing?
mathslover (mathslover):
\[\large{\frac{-6x}{-6}=\frac{27}{-6}}\]
\[\large{\frac{\cancel{-6}^1x}{\cancel{-6}^1}=\frac{-27}{6}}\]
mathslover (mathslover):
got my point?
OpenStudy (anonymous):
4.5

mathslover (mathslover):
-4.5 ?
mathslover (mathslover):
check that there is - sign
OpenStudy (anonymous):
would that be x=-4.5?
mathslover (mathslover):
right ..
mathslover (mathslover):
now can u graph the following coordinates on the graph :
(-4.5,0)
and (0,-9)

OpenStudy (anonymous):
I think so, it would be x(-4.5,0) and y(0,-9) right?
mathslover (mathslover):
right
OpenStudy (anonymous):
ok Thanks so much....now one more question, how do I give you a medal?
mathslover (mathslover):
there is best response written?
OpenStudy (anonymous):
yes
