Find the equation for a graph in the form y=mx+b when you are given two points on the graph.

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 calculations steps for finding the slope from the two points and then substituting the x,y coordinates to find the value of the y-intercept, b
(Repeating decimals, etc. are truncated in the sample problems to make them easier to read)
