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 yintercept, b
(Repeating decimals, etc. are truncated in the sample
problems to make them easier to read)
