Question

The parallelism condition for two straight lines one of which is specified by the equation $ax + by + c = 0$ and the other being represented parametrically by $x = {\rm{\alpha }}t + {\rm{\beta }},{\rm{\;}}y = {\rm{\gamma }}t + {\rm{\delta }},$ is given by

Accepted Answer

$a{\rm{\alpha }} + b{\rm{\gamma }} = 0$

Answer

$a{\rm{\gamma }} + {\rm{b\alpha }} = 0,{\rm{\;\beta }} = {\rm{\delta }} = {\rm{c}} = 0$

Answer

$a{\rm{\alpha }} - b{\rm{\gamma }} = 0,{\rm{\;\beta }} = {\rm{\delta }} = 0$

Answer

$a{\rm{\gamma }} = b{\rm{\alpha }} = 0$
