You can put this solution on YOUR website! Give the equation of the line which is parallel to y=-a/b x +c
EQN. OF A LINE PARALLEL TO THIS IS GIVEN BY Y=(-A/B)*X+CONSTANT
and passes through (o,d).SO ,THIS POINT SHOULD SATISFY THE ABOVE EQN.
D=(-A/B)*0+CONSTANT
CONSTANT=D....HENCE THE EQN. IS
Y=(-A/B)*X+D
