Point slope form is one such method used to find the straight line equation where one co-ordinate and slope is given. Here are two simple Point Slope Form Examples to find the equation of a straight line.

Let us consider the problem for practice : A straight line with X1 as 12, Y1 as 6 and slope as 2. What will be the equation of straight line?

We can calculate the equation using point slope form with the given formula.

**Substituting the values in the formula,**

(y - y1) = m(x- x1)
(y - 6) = 2(x- 12)
y - 6 = 2x - 24
y - 2x = -24 + 6
y - 2x = -18
**2x - y -18 = 0 is the equation of straight line**

Let us consider the problem for practice : A straight line with X1 as 7, Y1 as 2 and slope as 5. What will be the equation of straight line?

We can calculate the equation using point slope form with the above given formula.

**Substituting the values in the formula,**

(y - 5) = 5(x- 7)
y - 5 = 5x - 35
y - 5x = -35 + 5
y - 5x = -30
**5x -y -30 = 0 is the equation of the straight line.**
