A car’s fuel efficiency, in MPG, every year for 8 years is recorded in the table.

The linear equation y = -2.8x + 40 can be used to model the data in the table.

What is the meaning of -2.8 in terms of the context?

• The car’s fuel efficiency increases by about 2.8 mpg each year.

• The car’s fuel efficiency decreases by about 2.8 mpg each year.

• The car started with about 2.8 mpg when it was new.

• The car’s fuel efficiency decreases by exactly 2.8 mpg every year.
