The equation, y = 1250x + 22,850, gives the salary of a person as "y" after the stated number of years (x). Model the data with
Sidana [21]

Answer:

(a) y = 6250x +17850 --- The function

(b) y = 49100 --- The salary in 5 years

Step-by-step explanation:

Given

y = 1250x + 22850

Solving (a): Model the function around (1,24100) and (3,36600)

First, we calculate the slope

m = \frac{y_2 - y_1}{x_2 - x_1}

m = \frac{36600 - 24100}{3 - 1}

m = \frac{12500}{2}

m = 6250

The function is then calculated as:

y = m(x - x_1) + y_1

y = 6250(x - 1) + 24100

y = 6250x - 6250 + 24100

y = 6250x +17850

Solving (b): Salary in 5 years

Here:

x = 5

So:

y = 6250x +17850

y = 6250*5 +17850

y = 49100
