Relations Functions Linear Equations

A person travels by car.  They record their miles driven in a data table.  Calculate the linear regression equation of this data.

• y = 61.93x - 1.79

• y = -1.79x + 61.93

• y = 0.016x + 0.03

• y = 0.03x + 0.016

Is this set of ordered pairs a function and how can you tell?

• Yes its a function because no y values repeat

• No it's not a function because there are negative numbers

• No it isn't a function because an x value repeats but has different y values 

• No it isn't a function because an y value repeats but has different x values
