@TheSmartOne @wio please help?

anonymous · Answer

it means the slope

anonymous · Answer

the slope of 
$$y=mx+b$$ is $m$ so the slope of $y=3x-6$ is $3$

anonymous · Answer

the slope of 
$$ax+by=c$$ is 
$$m=-\frac{a}{b}$$

anonymous · Answer

@satellite73 wait is the slope of 2x + 3y = -9 is it positive or negative

anonymous · Answer

@Nnesha  2x + 3y = -9 is the slope positive or negative

nnesha · Answer

slope intercept form is y = mx +b here m is slope 
so you have to sole for y
 to do that you have to subtract 2x both
side 
when you subtract 2x both side what you should get ??

anonymous · Answer

3x = 11?

nnesha · Answer

nope you cannot combine -2x and -9
bec they are not like terms 
-2 have x and -9 doesn't have any variable 
so just write |dw:1420842323649:dw|
now divide both side by 3
