Question

The line of best fit through a set of data is y=13.743+3.814x

According to this equation, what is the predicted value of the dependent variable when the independent variable has value 170?

y = ______ Round to 1 decimal place.

Answer 1

HI Salma,

You need to plug 170 in for x to get the expected value of y. Thus:

y^=13.743 + 3.814(170)

y^=280.7

I hope this helps.
