Slope-Intercept Form Graphing Calculator

This was actually the first of my graphing projeccts. It graphs a line from slop-intercept form which is very commonly used in algebra. The slope is m but because the the is used as a fraction I made a variable for the denomenator as well. That variable can be set to any number including 1 which it often seems to be in algebra.

Standard Form Graphing Calculator

This is my latest math project which graphs a line using standard form. Like my other projects I programmed it on scratch.

Weekly Update 12/5/08

This week I accomplished my second graphing project that used point-slope form to graph. This form enaables you to graph the line by using a point the line goes through and the slope of the line. I have also started my third graphing project that graphs from standard form.

For next time I will again need to gather information about my project. Also there is no longer an xy grid backround on scratch so I will need to find my own.

Point-Slope graphing calculator

I programmed this project in scratch. it has the ability to graph a line based on one set of coordinates and a slope. Another thing I may do is have it figure out the slope itself from plugging in two sets of coordinates and using the slope equation:(Y2-Y1)/(X2-X1).

Week Plan

What are your in class goals/plans for the week?

There are three classes this week and my plan is that I will first gather my knowledge on graphing point-slope form. Then, I will work on my project and figure out the code. By the end of the week I will finish the project. At some point in the week I will browse other people's projects to get an idea for one of my own. I would figure out and write my own code for it though.
