Question

If (x, 3) and (3, 5) are the extremities of a diameter of a circle with centre at (2, y), then the values of x and y are

Options

  • (3, 1)

  • x = 4, y = 1

  • x = 8, y = 2

  • none of these

Solution

none of these

The end points of the diameter of a circle are (x, 3) and (3, 5).
According to the question, we have:

\[\frac{x + 3}{2} = 2, y = \frac{5 + 3}{2}\]

\[ \Rightarrow x = 1, y = 4\]
