Question

A formula in the formula y=mx+b models the value, y, of a new car x years after the initial purchase in 2017 . Would you expect b to be positive, negative, or zero

Answer 1

Answer:

I would expect m to be negative because as the number of years increase, the value of the car decreases.

Explanation:

Given the formula

y = mx + b

Where

y is the total value of the car

m represents the increase or decrease in value of the car

x is the number of years

b is the initial value of the car.

The formula for this question is

y = mx + 2017

I would expect m to be negative because as the number of years increase, the value of the car decreases.
