### Point slope form Calculator

To calculate equation of a straight line, please enter the line coordinates (x

_{1}, y

_{1}) in the XY plane are used and Enter Slope Value (m).

The point slope form is defined that the difference in the y-axis coordinate between two points (y - y

_{1}) on a line is proportional to the difference in the x-axis coordinate points (x - x

_{1}) and the proportionality constant m is the point slope of the straight line. The equation of a straight line can be found using following formula:

y – y

_{1}= m(x – x

_{1})
