MCQ
The locus of a point, whose abscissa and ordinate are always equal is:
  • ✓
    $x - y = 0$
  • B
    $x + y = 1$
  • C
    $x + y + 1 = 0$
  • D
    None of the above
✓

Answer

Correct option: A.
$x - y = 0$
Let the abscissa and ordinate of a point $“P”$ be $(x, y)$
Given condition: Abscissa $=$ Ordinate
$\text{(i.e) x = y}$
The locus of a point is $x - y = 0.$
