Answer:
2x + 3y = 0
Step-by-step explanation:
It is clear from the graph that the straight line passes through the point (0,0) i.e. origin.
So, in the slope-intercept form of the equation, there will be no y-intercept.
Hence, the equation of the straight line will be simply y = mx ...... (1)
Now, it is already shown in the graph that the straight line (1) passes through the point (3,-2) point.
So, from equation (1), -2 = 3m, ⇒
Therefore, the equation (1) becomes
⇒ 2x + 3y = 0 (Answer)
