The equation is y = 68.75x.
Step-by-step explanation:
The cost of petrol is Rs. 68.75 per liter.
Therefore, the cost of x liters of petrol is Rs. 68.75x.
If the cost of x liters of petrol is given by y, then we can write the equation
y = 68.75x.
This equation is a direct variation equation and geometrically it represents a straight line having slope 68.75 and it is passing through the origin. (Answer)
