Question

Find a point on 6x - 5y = 4 whose ordinate is twice the abscissa.

• A. (1, 2)
• B. (-1, -2)
• C. (2, 1)
• D. (-2, -1)

Answer 1

The correct option is B (-1, -2)

Given, x=2y
Let the required point be (a, 2a)

Since it passes through the line, it will be a solution of the equation 6x – 5y = 4

Putting (a, 2a) in the equation, we get

6a – 10a = 4

-4a = 4

a = -1

The required point is (-1, -2)
