Linear Equations
Find the equation for a graph in the form
y
=m
x
+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)
