Answer 2

Answer:

y = 8 + x

Step-by-step explanation:

A linear equation is of the form:

y = mx + c

where,

y = dependent variable

x = independent variable

m = rate

c = constant

In this case:

y = present price of petrol

x = Number of years = 2

m = Rs. 4 per litre

c = x, price of petrol in December, 2011

∴ y = 4(2) + x

y = 8 + x
