Question

The points $(6,12)$ and $(0,-6)$ are connected by a straight line. Another point on this line is:

• A. (3, 3)
• B. (2, 1)
• C. (7, 16)
• D. (-1, -4)

Answer 1

Answer: (A)

(3, 3)

Equation of the line joining (6, 12) and (0, -6)

$⟹(y-12)=\left(\frac{12-(-6)}{6-0}\right)(x-6)⟹(y-12)=3(x-6)⟹y-12=3x-18⟹y=3x-6$

(3, 3) is another point on the line $y=3x-6$
