Question

If segment AB is parallel Y-axis and coordinates of A are (1, 3), then the coordinates of B are ______.

Options

• (3, 1)

• (5, 3)

• (3, 0)

• (1, –3)

Answer 1

If segment AB is parallel Y-axis and coordinates of A are (1, 3), then the coordinates of B are (1, –3).

Explanation:

Since, seg AB || Y-axis.

∴ x co-ordinate of all points on seg AB will be the same.

x co-ordinate of A (1, 3) = 1

x co-ordinate of B (1, –3) = 1

∴ (1, –3) is option correct.
