Question

slope: -3
y - intercept: 0

Explanation:

Step1: Recall slope-intercept form

The slope-intercept equation of a line is $y = mx + b$, where $m$ is the slope and $b$ is the y-intercept.

Step2: Substitute given values

Substitute $m = -3$ and $b = 0$ into the formula:
$y = -3x + 0$

Step3: Simplify the equation

Simplify the expression to get the final line equation.
$y = -3x$

Answer:

$y = -3x$
