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)
