Linear Equations: Find the slope and the equation for a graph in the form y=mx+b when you are given two points on a graph.
Directions: Enter the points in the form x,y with no spaces, for example, 3,4 or -2.3,5.72 The large text window will show the calculation steps for finding the slope(m) from the two points and then will substitute the x,y coordinates to find the value of the y-intercept, b (Repeating decimals, etc. are truncated in the sample problems to make the values easier to read)
