Question

Any point on the line y=3x is of the form

Answer 1

Answer:

(a,3a) will be the answer.

Answer 2

Any number on the line y = 3x is of the form (a, 3a), where a is any real number.

Explanation:

• The given straight line is y = 3x. Let us find some points on this line and check their forms.

1. When x = 1, y = 3.
2. When x = 2, y = 6.
3. When x = 3, y = 9.
4. When x = 4, y = 12.

• and so on ... ...

We see that the ordinate of each point is three times its abscissa.

In general, we can take the points to be of the form (a, 3a), where a is any real number.
