The equation of the straight line joining the origin to the point of intersection of \( \Large y-x+7=0\ and\ y+2x-2=0 \)is:

A) \( \Large 3x+4y=0 \)
B) \( \Large 3x-4y=0 \)

C) \( \Large 4x-3y=0 \)
D) \( \Large 4x+3y=0 \)

Correct answer:
D) \( \Large 4x+3y=0 \)

Description for Correct answer:
The intersection point of \( \Large y-x+7=0 \) and \( \Large y+2x-2=0 \) is \( \Large \left(3,\ -4\right) \)

Therefore, Equation of straight line joining from origin to the point \( \Large \left(3,\ -4\right) \) is

\( \Large y-0 = \frac{-4}{3} \left(x-0\right) \)

=> \( \Large 3y = -4x => 4x+3y=0 \)
