Question

If the points A (2,0), B (-6,0), C (3, a–3) lie on the x-axis then the value of a is _____
(a) 0 (b) 2 (c) 3 (d) –6

Answer 1

Answer:

The value of a is 3.

Step-by-step explanation:

We know that if a point lies on the x-axis then the y-coordinate of the point is zero.

We'll use this concept to find the value of 'a'.

Since, the point C(3,a-3) lie on the x axis. Hence, its y-coordinate must be zero.

The y -coordinate is a-3. Hence, we have

a - 3 = 0

a = 3

Thus, the value of a is 3.

c is the correct option.
