How to Find the Equation of a Line Through Two Points
In Zoom Math 200 and above, you can find the equation of a line through two points by typing the two points separated by a comma. For example, to find the equation of the line through the points (0,4) and (3,5), just type (0,4),(3,5).
In the rare case where one of the points has a three-digit y-coordinate, this won’t work. For example, if you type (0,4),(3,100), Zoom Math doesn’t realize that (3,100) is a point; instead, it thinks that (3,100) is just the number 3,100 in parentheses. If you have that problem, just write “.0” at the end of the x-coordinate. For example, if you type (0,4),(3.0,100), Zoom Math gets the right answer.

"Your programs were instrumental in helping me pass and more importantly, understand, the Algebra and Business/Finance math courses that I had to take to obtain my Associates degree." - Mark C. Buffalo, NY
"Prior to teaching myself with Zoom Math my ACT on the math section was 24 three times in a row. After studying the problems I missed with Zoom Math's Trace feature as my guide I was able to pull my math section of the ACT up to a 31. I now have a 30 composite score and a full ride to the University of Alabama and you guys are 100% responsible!" - Andrew T., Sacramento, CA
"We received my son's MCT scores from 10th grade (end of last year). He jumped 3 levels and scored highest in his class." - Kathy J. Austin, TX
"I completed my math course 6 1/2 weeks ahead of time. It would not have been possible without your ZOOM 300 SOFTWARE. If I had your product at the beginning of my 24 week course I would have completed this course within 2 weeks." - Bernard P., Los Angeles, CA
