Explanation:

Slope-intercept form: →
y=mx+b

The y-intercept is the point on a graph at which the graph crosses the y-axis.

Used: Rise/Run


m=(rise)/(run)= (y-b)/(x-0)

-5 is the slope.

-21 is the y-intercept from the slope-intercept form.

Hope this helps!

Thanks!

Have a great day!

slope intercept form of a line is

y = mx+b

where m is the slope and b is the y intercept


y=5x-21

5 is the slope and -21 is the y intercept
