# Chapter 3 - Section 3.4 - The Slope of a Line - Exercise Set: 31

The slope of the line is -2 and the y-intercept is (0,7)

#### Work Step by Step

We are given that $2x+y=7$. We can transform this equation into the slope-intercept form $y=mx+b$, where m is the slope and the point (0,b) is the y-intercept of the line. First, subtract 2x from both sides. $y=-2x+7$ $m=-2$ and $b=7$ Therefore, the slope of the line is -2 and the y-intercept is (0,7).
