For the equation $3 x + 4 y = 0$ , a student plots solutions.
Which statement is true about its graph?

Class 9Solutions of a Linear EquationLinear Equations

AIt passes through the origin (0, 0)
BIt never touches either axis
CIt is parallel to the $x$ -axis
DIt is the same as $x = 0$

Step-by-Step Solution

Put

x = 0, y = 0

: 0 + 0 = 0, true. So (0, 0) is a solution and the line passes through the origin.

Answer: A) It passes through the origin (0, 0)
