Question

Help me please ;-;

Part A.

find an equation for the line of best fit

Part B.

predict the cost to raise a child born in 2011.

Year Born(x):1988, 1991, 1994, 1997, 2000

Annual Cost(y): 10,700, 11,700, 12,600, 15,000, 16,700

Answer 1

The equation of line of best fit for the data is:

• y = 510x - 1003600

According to the data, the child born in 2011 is 22,0110

How to find the prediction

The equation of line of best fit is gotten using technology to be:

y = 510x - 1003600

Using the equation, the prediction is done as follows:

Substitute x = 2011 into the equation

y = 510x - 1003600

y = 510 (2011) - 1003600

y = 22,0110
