Answer:
[tex]\huge\boxed{\mathrm{Yes.}}[/tex]
Step-by-step explanation:
If the two lines are perpendicular, Multiplying their slopes must give the result of -1.
So, Let's Multiply these slopes.
=> [tex]\sf -\frac{2}{9} * \frac{9}{2}[/tex]
=> -1
Since, the result of multiplying these slopes give -1, So, the two lines are perpendicular.
