What can be used to predict diameter, given family income

We can see (by observation) that the data on the table can only be represented on a scattered plot, and scattered plot uses regression equation for data prediction.

i.e. --- equation of line of best fit

In this case;

When the x value (income) is known, we can simply plug in the value in the above equation to get the y value (diameter)

is it 35
