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) |
