L_{1} and L_{2} are two lines which intersects

each other at a right angle at the

point (1, 3), L_{1} cuts the y - axis at

the point (0, 2) find the equations of L_{1} and L_{2}

e q n L_{1} y - 3 = \frac{2 - 3}{0 - 1} (x - 1)

y - 3 = (x - 1) y - x - 2 = 0

s l o p e L_{1} = 1 s l o p e L_{2} = - 1 [m_{1} m_{2} = - 1]

e q n L_{2} y - 3 = (- 1) (x - 1)

y - 3 = - x + 1

y + x - 4 = 0
