Question

practice: 9. identify the slope and y-intercept of $y = -3x + 7$.

Explanation:

Step1: Recall slope-intercept form

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

Step2: Match given equation to form

Compare $y = -3x + 7$ with $y = mx + b$. Here, $m = -3$ and $b = 7$.

Answer:

Slope: $-3$
y-intercept: $7$ (or the point $(0, 7)$)
