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

Explanation:

Slope-intercept form: → [tex]y=mx+b[/tex]

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

Used: Rise/Run

[tex]m=\frac{rise}{run}= \frac{y-b}{x-0}[/tex]

-5 is the slope.

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

Hope this helps!

Thanks!

Have a great day!
