The cost of labour per hour is $90.56
The total amount paid by Austin is the sum of the total cost of labour and the cost of the parts
Total amount paid = total cost of labour + cost of parts
$553.50 = total cost of labour + $126
total cost of labour = $533.50 - $126
= $407.50
The total cost of labour = cost of labour per hour x total time worked
$407.50 = xx × 4.5
xx = $407.50 / 4.5
xx = $90.56

The line of the best fit is shown in the picture which is approximate near the dots.
<h3>What is the line of best fit?</h3>
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
The slope and y-intercept can be found using the formula below:

We have a given a scatter plot shows the data for NCAA quarterbacks comparing their attempted passes to completed passes.
We can draw a line of best fit y = mx + c
Thus, the line of the best fit is shown in the picture which is approximate near the dots.
