Question

find the equation of the line.
use exact numbers. for a negative y - intercept, type a negative sign.
$y = \square x + \square$

Explanation:

Step1: Identify y-intercept

The line crosses the y-axis at $(0, -3)$, so $b=-3$.

Step2: Calculate slope

Use two points $(0, -3)$ and $(6, 0)$. Slope $m=\frac{0-(-3)}{6-0}=\frac{3}{6}=\frac{1}{2}$.

Step3: Write line equation

Substitute $m$ and $b$ into $y=mx+b$.

Answer:

$y=\frac{1}{2}x-3$
