Line of Best Fit Linear

A person travels by car. They record their miles driven in a data table. If a person has been driving for 8 hours, how far have they gone? (Round to nearest whole mile)

• About 484 miles

• About 494 miles

• About 498 miles

• About 500 miles

• y = 5

• x = 5

• y = 5x + 7.5

• y = 7.5x + 5

• y = -7

• x = -4

• y = -4x - 7

• y = -7x - 4

• y = -2x + 3

• y = 3x - 2

• x = 3

• y = -2

Estimate the correlation coefficient for this scatterplot.

• r = 1.2

• r = 0.89

• r = 0

• r = -0.89

Estimate the correlation coefficient for this scatterplot.

• r = -0.9

• r = 1

• r = 0.9

• r = -1

Use DESMOS to find the correlation coefficient (round to the nearest hundredths)

(do not type in "r", only type the value)

Use linear regression to formulate an equation that can be used to model the relationship between the runner's distance and the time in minutes based on the information provided on the table.
