Question

3. Write an equation of best fit for the given data.

Answer 1

The equation that best fits the data is a linear equation.

The general formula for linear equations is,

`y=ax+b`

Let us plot the data on a graph

Hence, from the graph we obtain

`\begin{gathered} a=1.86634 \\ b=82.2911 \end{gathered}`

Let us now substitute the values of a and b into the general equation

`y=1.86634x+82.2911`

Hence, the equation that best fits the given data is

`y=1.86634x+82.2911`
