Question

What.is the y intercept of a line given by the equation y=5×-21?

Answer 1

Answer:

-21

Step-by-step explanation:

If the equation of the line is

$y=mx+b,$

then $m$ is the slope of the line and $b$ is the y-intercept of the line.

In your case, the equation of the line is $y=5x-21.$

So, the slope of this line is $m=5$ and the y-intercept is $b=-21.$
