Answer 1

A linear regression is a regression that can be represented by a linear line of best fit.

The equation of the line of best fit is $y = 2.4x +33.2$

How to determine the equation

From the graph, we have the following ordered pairs

(x,y) = (50,150) and (100,270)

The slope (m) is then calculated as:

$m = \frac{270 - 150}{100 - 50}$

This gives

$m = 2.4$

The regression line crosses the y-axis at b = 33.2

A linear regression is represented as:

y = mx + b

So, we have:

$y = 2.4x +33.2$

Hence, the equation of the line of best fit is $y = 2.4x +33.2$
