A ray of light is incident along a line which meets another line, $\displaystyle 7 x-y+1=0$, at the point $\displaystyle (0, 1)$. The ray is then reflected from this point along the line, $\displaystyle y+2 x=1$. Then the equation of the line of incidence of the ray of light is :
Official answer
(1)
$\displaystyle 41 x-38 y+38=0$
