In the worked examples in the next section Ill use the point-slope formula because thats the way I was taught and thats what most books wantBut my experience has been that many students prefer to plug the slope and a point into the slope-intercept form of the line and solve for bIf that works better for you then use that method instead. Substitute the point you found x 1 y 1 into the point slope formula. Click the blue arrow to submit.
And m represents the slope of the line.
The formula to calculate slope is given as Slope of a Line m y2 - y1 x2 - x1 Where m is the slope of the line. To use this formula you will substitute the coordinates of the known point for the x sub 1 and the y sub 1. Remember m is the same in both slope intercept and point slope forms so you can take the directly from the slope intercept equation. And m represents the slope of the line.
