Question 432328
I have a complete explanation on this topic on my website.  To find my website click on my tutor name "rapaljer" anywhere in algebra.com.  There you will find a link to take you to my website.  On the Homepage of my website, look for the link near the top of the page "Basic, Intermediate, and College Algebra: One Step at a Time."  Next, click on "Intermediate Algebra", then look in Chapter 5, amd click on Section 5.03 Finding the Equation of a Line.  Look for problems #33 and 34.  Then near the top of this page there is a link to my "Math in Living Color" pages where these problems are solved in detail IN COLOR!!
