Make a scatter plot of the data:

1

Write the linear equation that models this situation.

1

What is the monthly service fee?

1

What is the installation fee?

1

Make a scatter plot of the data and make a line of best fit.

1

positive correlation

negative correlation

relatively no correlation

1

Write the equation of the line (determine by hand). You can check your answer with the graphing calculator to check if it is reasonable.

1

Use your equation from #38 to estimate the time it would take to roast a 10 pound turkey.

1

Is this interpolation or extrapolation?

Extrapolation because 10 is between 8 and 12 pounds.

Interpolation becuase 10 is outside the other data points.

Interpolation because 10 is between 8 and 12 pounds.

Extrapolation because 10 is outside the other data points.

direct variation

inverse variation

Equation of the data?

Equation of the data?

Select three points that would create direct variation:

Direct variation equation?

Select three points that would create inverse variation:

Inverse variation equation?

100-watt

200-watt

Why?

Constant of variation?

Direct variation equation?

Inverse variation equation?

Compare the slopes:

The slope of g(x) is larger than the slope of f(x).

The slope of g(x) is smaller than the slope of f(x).

The slope of g(x) is equal to the slope of f(x).

Compare the y-intercepts:

The y-intercept of g(x) is more than the y-intercept of f(x).

The y-intercept of g(x) is less than the y-intercept of f(x).

The y-intercept of g(x) is equal to the y-intercept of f(x).

Use your graphing calculator to find the equation of the line. Round your slope and intercept to the hundredths place.

Using your equation from #43, predict the gas mileage for a car that weighs 4400 pounds (4.4 thousand pounds). Round to the nearest hundredths place.

This is extrapolation because 4.4 is within the data.

This is interpolation because 4.4 is within the data.

This is interpolation because 4.4 is outside the data.

This is extrapolation because 4.4 is outside the data.

Use your equation from #43 to predict the weight of a car that has the gas mileage of 30 miles per gallon (replace y with 30!)

This is interpolation because 30 mpg is within the data.

This is extrapolation because 30 mpg is within the data.

This is interpolation because 30 mpg is outside of the data.

This is extrapolation because 30 mpg is outside of the data.
