• POINT SLOPE FORM

2
Equation of Straight Line

• We know to find the equation of the
  straight line with the Slope intercept form.
• Y mx c
• Standard Form
• Ax By c
• Now, a more easier way to find the
  equation of straight line with
  Point Slope Form.

3
Point Slope Form

• Point slope form is one of the forms used
  to express the equation of straight
  line.
• When the slope and one of the co-ordinate
  points of the straight line are known,
  then you can find the equation of the
  straight line.
• Besides other methods, it is easy to find
  the equation with point slope form.

4
Point Slope Form Equation

• The equation of the point slope form can
  be calculated with the formula
• y y1 m ( x- x1)
• where,
• m Slope
• (x1, y1) Coordinate points

5
Point Slope Form Equation Calculation

• Consider a straight line with co-ordinate points
  (2,10) , (5,1) and slope -3.

6
Point Slope Form Equation Calculation

• Consider any one of the co-ordinate
  points. Let us take (2,10) and slope m -3.
• Substitute the values in the formula of
  point slope form.
• y 10 -3 ( x 2)
• y 10 -3x 6
• - y - 3x 6 10
• Hence the equation is 3x y 16 0

7
Point Slope Form Without Slope

• You can also find the equation of the
  straight line without slope, when two
  co-ordinate points (x1, y1) and
  (x2, y2) are given.
• (y y1) / (y2 y1) (x x1) / (x2
  x1)
