#### Answer

slope = $-2$
y-intercept: $(0, 7)$
Refer to the graph below.

#### Work Step by Step

RECALL:
The slope-intercept form of a line's equation is $y=mx+b$ where $m$=slope and $(0, b)$ is the line's y-intercept.
Thus, the equation $y=-2x+7$ has a slope of $-2$ and a y-intercept of $(0, 7)$.
To graph the equation, perform the following steps:
(1) Plot the y-intercept $(0, 7)$.
(2) Use the slope to plot a second point.
Since the slope is $-2$, from $(0, 7)$, move 2 units down (the rise) and 1 unit to the right (the run) to reach the point $(1, 5)$. Plot $(1. 5)$.
(3) Connect the points using a straight line.
