Question 820877: Write an equation in point-slope form of the line that passes through the given point and has the given slope m:
2. (-11,-3), m = -9
Would you please also work out the problem so i know and understand how to do it in the future?

The form of the general point-slope equation is:

= the slope of the line
= the y-intercept
-----------------------
The slope is always m = ( change in y ) / ( change in x )
In the following formula, is ANY
and is ANY
----------------------
given the point (-11,-3) and
----------------------------------

This is just ( change in y ) / ( change in x ) = m




-----------------
This is now in the form
check: does it go through the point ( -11,-3 )?



OK
Here's a plot of the line:
