Y=mx+b
OpenStudy (anonymous):
M is the slope
OpenStudy (anonymous):
oh sry a.1/3 b.-3 c.-1/3 d.3
B.
C.
D.

As @ayeshaafzal221 says, when the equation is in the form of y = mx + b, M is the slope. So put the equation into this form and what do you get?
OpenStudy (anonymous):
but im not shure what m x and b means

b is a constant where the graph cuts the y-axis when x = 0, and m is the slope of the graph.
OpenStudy (anonymous):
okay, but what would i do then?
OpenStudy (anonymous):
im sry i really have no idea how to do this :/

$$\Huge 2x – 6y = 9$$
$$ \Huge 2x – 6y +6y= 9+6y$$
$$ \Huge 2x = 9+6y$$
$$ \Huge 2x-9 = 9+6y-9$$
$$ \Huge 2x-9 = 6y$$
$$ \Huge \frac{1}{6} ( 2x-9) = \frac{1}{6} 6y$$
$$ \Huge \frac{1}{3} x- \frac{3}{2} = y $$
