someone solve it pls fast.......​

Answer 1

Answer:

a = -9.

Step-by-step explanation:

Mid-point P of QR is given by: $P = (\frac{x_{Q} + x_{R}}{2}, \frac{y_{Q} + y_{R}}{2})$

So, $P = (\frac{-5 - 1}{2}, \frac{4 + 0}{2}) = (\frac{-6}{2}, \frac{4}{2}) = (-3, 2)$

Now, P is represented as $(\frac{a}{3}, 2)$

Comparing with the actual value we obtained,

$(\frac{a}{3}, 2) = (-3, 2)$

Or, $\frac{a}{3} = -3$

Or, $a = -3 * 3 = -9$
