Chapter 3 - Section 3.4 - The Slope-Intercept Form of the Equation of a Line - Exercise Set: 21

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
