Question:

If point (x, y) is equidistant from the points (7, 1) and (3, 5), then which one of the following options is correct?

Options:

$x-y=2$

$x+y=2$

$x-y=1$

$x-y=-2$

Correct Answer:

$x-y=2$

Explanation:

We know that,

Distance formula = √((x−7)2+(y−1)2)

= √((x−3)2+(y−5)2)

⇒−14x + 49 − 2y + 1= −6x +9 − 10y + 25

⇒ 8x − 8y = 16

⇒ x−y = 2
