Answer
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).
