Exercise 11 Page 246

Equations in Slope-Intercept Form follow a certain format. In this form, $m$ is the slope and $b$ is the $y\text{-}$intercept. The line has a slope of $\text{-}4,$ so we substitute $m=\text{-}4.$ Since the $x\text{-}$coordinate of the given point equals $0,$ its $y\text{-}$coordinate $0$ is the $y\text{-}$intercept $b$ of the equation. Now that we have both slope and $y\text{-}$intercept, we can write the final equation. This corresponds to the answer C.
