will represent this linear model shown in the data table.
<h3>What will be the linear model for the given data?</h3>
Put the values of the x in the all given equations and then check the value of y if the value of y matches the given values in the option
So if we put the value x=1980 in the then
These values are closest to 70.1 whereas other options do not satisfy the condition.
Thus will represent this linear model shown in the data table.
