9.10 The Point Slope Form of a Line

The equation of a line passing through a point P(x1 , y1) having a slope m is (y - y1) = m(x - x1).
This form of a line is called the Point-Slope form.

Example:
Find the equation of a line passing through (3,5) having a slope 3.
Solution:
Given that slope is 3
i.e., m = 3
A point on the line is (3,5)
Using the point slope form equation,
i.e., (y - y1) = m(x - x1).
y - 5 = 3(x - 3)
y - 5 = 3x - 9
y = 3x - 9 + 5
y = 3x - 4
Therefore, y = 3x -4 is the required equation of the line.


Directions: Solve the following questions. Also write at least 10 examples of your own.
Q 1: Find the equation of a line passing through (3,7) having a slope 2.
y = 2x + 1
y = 2x - 1
y = 2x + 3

Q 2: Find the equation of a line passing through (5,8) having a slope 4.
y = 4x - 6
y = 4x + 12
y = 4x - 12
y = 4x + 6

Q 3: Find the equation of a line passing through (3,8) having a slope 6.
y = 6x - 7
y = 6x + 8
y = 6x + 10
y = 6x - 10

Q 4: Find the equation of a line passing through (7,14) having a slope 2.
y = 2x + 6
None of these
y = 2x - 6
y = 2x

Q 5: Find the equation of a line passing through (3,9) having a slope 3.
y = 3x
y = 3x - 9
y = 3x + 9

Q 6: Find the equation of a line passing through (7,6) having a slope 3.
y = 3x - 7
y = 3x - 8
y = 3x - 15
