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) Find the equation from two points on a grid: Enter Point 1 (x 1 ,y 1 )   Enter Point 2 (x 2 ,y 2 ) slope (m) = The equation is: ©Jeff LeMieux, 2002
