What is the equation of a line passing through (0,4) with slope -2?

Question

Accepted Answer

1. Use slope-intercept form: $y=mx+b$, where $m$ is the slope and $b$ is the $y$-intercept.
2. Here $m=-2$. The line goes through $(0,4)$, so $b=4$.
3. Substitute to get $y=-2x+4$.
4. This matches option **(a)**.
