Answer
y=-$\frac{2}{9}$x
m=-$\frac{2}{9}$
y-intercept=0
Work Step by Step
First isolate y in the given equation.
2x+9y=0
2x-2x+9y=0-2x
9y=-2x
$\frac{9y}{9}$=-$\frac{2x}{9}$
y=-$\frac{2}{9}$x
y=-$\frac{2}{9}$x+0
Now that the equation is in the form of y=mx+b you can see than m=-$\frac{2}{9}$ and y-intercept=0
