Question

Write the equation of the line through the point (1,-1) and (3,5) 


Solution

Given : $$ (x_{1}, y_{1} ) = (1,-1) ; (x_{2} , y_{2} ) = (3,5)$$
$$\therefore $$ Required equation is of the form $$y -y_{1} = \dfrac{y_{2} - y_{1}}{x_{2}-x_{1}} (x - x_{1}) $$ (two -point form )
$$i.e, y + 1 = \dfrac{5-(-1)}{3-} (x-1)$$
$$i.e, y + 1 = \dfrac{6}{2} (x-1)$$
$$i.e, y +1 = 3x -3 i.e, 3x - y -4 = 0$$
