Question

which is the equation of a line whose slope is -2 and whose y-intercept is 3?
○ $y = 3x + 2$
○ $y = 2x - 3$
○ $y = 3x - 2$
○ $y = -2x + 3$

Explanation:

Step1: Recall slope-intercept form

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

Step2: Substitute given values

Substitute $m = -2$ and $b = 3$ into the formula:
$y = (-2)x + 3$
Simplify to get $y = -2x + 3$

Answer:

$y = -2x + 3$
