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