Point slope calculator is an online tool developed to find the equation of a straight line using the slope and point on that line.

What is point-slope?

Point slope form is a general form for linear equations. It highlights the slope of the line and a point on the line. You can find the equation in the below section.

Point slope formula

The point slope equation can be expressed as:

y - y1 = m(x- x1)


m is the slope, and

x1y1 are the coordinates of a point.

How to find equation of a line?

To find equation of a straight line without a slope intercept form calculator, follow the below example.


Find the equation of a line whose known points are (2, 3) and slope of line is 8.


Step 1: Identify and write down the values.

x1 = 2

y1 = 3

m = 8

Step 2: Place the values in the point slope formula and solve the equation.

y - y1 = m(x- x1)

y – 3 = 8(x - 2)

y – 3 = 8x – 16

8x – 16 – y + 3 = 0

8x – 13 – y = 0

y = 8x – 13
