POINT – SLOPE FORM

Slide 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.

Slide 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.

Slide 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

Slide 5

Point Slope Form Equation Calculation Consider a straight line with co-ordinate points (2,10) , (5,1) and slope -3.

Slide 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

Slide 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)
