Slope Calculator

This app calculates the slope of a line by accepting the parameters (x1, y1) and (x2, y2). The slope calculator has a graphing function that plots the line on the Cartesian grid and gives the lines slope. The graph can be manipulated by dragging its points. The plotting function is limited to the size of the device screen the app is running on. It will still display the correct line.
This app is a learning aid for students learning algebra to easily calculate slope, and connect how slope is affected by manipulating the position of two points on a line.
