If you know the rise and run of a line you can calculate its slope using the slope formula. So together we are going to learn how to. Enter the point and slope that you want to find the equation for into the editor.
One point on the line.
If the coordinate point and slope values are known the line equation can be easily found. Point-slope is the general form y-y₁mx-x₁ for linear equations. The first step will be to use the points to find the slope of the line. To plot the graph you have to identify m the slope the x intercept x1 and the y intercept y1.
