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