Answer
y=-$\frac{2}{7}$x
m=-$\frac{2}{7}$
y-intercept=0
Work Step by Step
First isolate y in the given equation.
2x+7y=0
2x-2x+7y=0-2x
7y=-2x
$\frac{7y}{7}$=-$\frac{2x}{7}$
y=-$\frac{2}{7}$x
y=-$\frac{2}{7}$x+0
Now that the equation is in the form of y=mx+b you can see than m=-$\frac{2}{7}$ and y-intercept=0
