Question

Using Desmos, enter the data from the table and create a linear regression equation. Let x = time in years since

1900 and let y = minimum hourly wage. Remember, the line that is graphed is a “line of best fit” or a “trend line.”

The equation for that line is called a linear regression equation. Use the information given to you by desmos to

write the linear regression equation. Do not round.


Use the equation to estimate the minimum hourly wage of a U.S. worker in 2025. Use Desmos and round to the

nearest cent.

Minimum hourly wage =

Answer 1

$8.61 (nearest cent)

Explanation:

The graphed data with the line of best fit (attached).

From the graphing calculator, the given line of regression is:

y = 0.125873x - 7.11916

To estimate the minimum hourly wage in 2025:

⇒ x = 2025 - 1900 = 125

Substitute x = 125 into the equation:

⇒ y = 0.125873(125) - 7.11916

⇒ y = 8.614965

Therefore, minimum hourly wage = $8.61 (nearest cent)
