Question

the age and hourly pay of five employees at a store are shown in the table. a line of best fit for the data is y = 0.9x - 4.5, where x represents age, in years, and y represents hourly pay, in dollars. based on the data, what is the best prediction for the hourly pay of a 25 - year - old? a. $17.50 b. $18.00 c. $19.00 d. $22.50 e. $32.78

Explanation:

Step1: Identify the value of x

The age $x = 25$ years.

Step2: Substitute x into the equation

Substitute $x = 25$ into $y=0.9x - 4.5$. So $y=0.9\times25- 4.5$.

Step3: Perform multiplication

$0.9\times25 = 22.5$. Then $y = 22.5-4.5$.

Step4: Perform subtraction

$22.5-4.5=18$.

Answer:

B. $18.00$
