Question

1. when the equation of a line is in the form $y = mx + b$, what does b represent?

• slope
• none of these
• x-intercept
• y-intercept

Explanation:

In the slope-intercept form of a line $y=mx+b$, $m$ is the slope, and $b$ is the value of $y$ when $x=0$, which is the y-intercept (the point where the line crosses the y-axis).

Answer:

y-intercept
