Question

Tim explained a function in words and Paul wrote an equation.

Answer 1

The correct statement regarding which linear function has the lowest y-intercept is given by:

Tim’s with a y-intercept of $2,780

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

• m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

• b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For Tim's account, we have that:

m = 225, y(8) = 4580, hence:

y = 225x + b.

4580 = 225(8) + b

b = 4580 - 225(8)

b = $2,780.

For Paul's account, the y-intercept is given by:

y = 1400 + 56(26) = $2,856.

Hence the correct statement is:

Tim’s with a y-intercept of $2,780
