The function that describes the situation where a delivery service charges a base fee of $8 plus $1.50 for each mile delivered is linear.

Here’s why:

Linear Function: The total cost is determined by adding a fixed base fee ($8) to a variable cost that depends on the number of miles delivered ($1.50 per mile). This means the total cost increases in a straight-line manner with respect to the number of miles.

The general form of a linear function is:

y = mx + b

where:

m is the rate of change (in this case, $1.50 per mile),

x is the number of miles delivered,...
