SolutioN :

\: \: \: \: \: \sf \: putting \: \: \: \: x= -4 \: \: \: \: \& \: \: \: \: y= -6puttingx=−4&y=−6

\mapsto \sf 3 \times ( - 4) - 4 \times ( - 6)↦3×(−4)−4×(−6)

\: = \sf \: 12=12

\begin{gathered} \therefore \sf \: As \: \: LHS \: \: is \: \: equal \: \: RHS \: \: we \: \: can \: \: say \: \: pt \: (-4,-6) \: exist \: \: in \: \: the \: \: line \\ \\ \\ \large{ : { \underline{ \boxed{ \mathfrak{Proved }}}} : }\end{gathered}
