If point (x, y) is equidistant from the points (7, 1) and (3, 5), then which one of the following options is correct? |
$x-y=2$ $x+y=2$ $x-y=1$ $x-y=-2$ |
$x-y=2$ |
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 |
