# 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})

Now we can apply these values in given formula as follows:

y – y

_{1}= m(x – x

_{1})

=> y - 8 = 5(x - (-6))

=> y - 8 = 5(x + 6)

=> y - 8 = 5x + 30

=> 5x + 30 -y + 8

= 5x - y + 38 (is the line equation)
