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