Equation for the line of best fit:


Each step of my work to find the equation:








What does the slope represent within the context of your graph?





What does the y-intercept represent?






Test the residuals of two other points to determine how well the line of best fit models the data.



Use the line of best fit to help you describe the correlation.




Using the line of best fit that you found in Part 3, Question 2, approximate how tall is a person whose arm span is 66 inches?




According to your line of best fit, what is the arm span of a 74-in-tall person?

kirill [66]

Answer:

<em>Felix earns total $594 per week.</em>

Step-by-step explanation:

Felix’s sales are $53000.

So, <u>the amount of sales over $4800 will be</u>:  \$53000-\$4800= \$48200

Felix earns $450 per week and additional 3% of sales over $4800.

So, his additional income = (\$4800\times 0.03)=\$144

Thus, Felix's total income will be:  (\$450+\$144)=\$594

We have slope intercept form.  Parallel means the same slope, and we get to choose the intercept to fit the new point (-6,0).

y = (1/3) x + b

0 = (1/3) (-6) + b

2 = b

Answer y = (1/3) x + 2 third choice
