earn , learn, control, take, report, gallop, come , paralyze, replace, manipulate

Price of essential is such a crucial factor that it directly (a) — the life and living of the majority people. The measures so far (b) -- by the government (c) -- appreciation from the people. But it is (d) - by despair as the majority of the people () - under the cursing burden of (f) - prices. It (g) that the business syndicate (h) - the market prices and the retailers (1) out of their evil lust. Moreover, the enforcement bodies are () - to have been involved in illegal extortionist.

Answer 2

Let the given points be represented by A(-3, 1), B(-6, -7), C(3, -9) and D (6.-1).

We know that if a pair of opposite sides of a quadrilateral are parallel and congruent, then it is a PARALLELOGRAM.

The lengths of the opposite sides AB and CD are calculated, using distance formula, as follows :

$</p><p>AB={(-6+3)^2+(-7-1)^2}={9+64}={73},\\\\CD={(6-3)^2+(-1+9)^2 }=\sqrt{9+64}={73}</p><p> </p><p>$

And, the slopes of the sides AB and CD are calculated as follows :

• Since the lengths and slopes of a pair of opposite sides AB and CD are equal, so ABCD is a parallelogram.

Hence showed.
