Equation of a straight line can be calculated using various methods such as slope intercept form, point slope form and two point slope form method. Point slope method is one such method used to find the straight line equation when one co-ordinate and slope is given. Use the online analytical point slope form calculator to find the equation of the straight line using the Point-Slope Method. The Point slope method uses the X and Y co-ordinates and the slope value to find the equation. The 'b' value (referred as y-intercept) is where the line crosses the y-axis. Enter the X and Y co-ordinates, slope value in the point slope form calculator to find the equation of straight line.

Formula :

(y - y1) = m(x- x1)

Example

Find the equation of a straight line when the co-ordinate point is (3,4) and slope is 7.

Step 1

We know that, (x1,y1) = (3,4). Substitute the values in (y - y1) = m(x- x1)
(y-4) = 7 ( x-3)

Step 2

On Simplifying,
(y-4) = 7x - 21
y-7x = -21 + 4
y-7x = -17
7x-y-17 = 0 is the equation.
