Answer
a. $y=(0)x-7$.
b. $m=0$, $b=-7$
c. See figure.
Work Step by Step
a. Given $4y+28=0$, we can rewrite the equation in slope-intercept form as $y=(0)x-7$.
b. The slope can be found as $m=0$ and the y-intercept can be found as $b=-7$.
c. With the slope and y-intercept, we can graph the linear function as shown in the figure.
