y=8x+20

Step-by-step explanation:

The line that best fits is shown in the given graph.

To find the equation that represent that red line, we first have to find its slope and then use the point-slope formula.

The slope is defined as

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

We are gonna use points (0,20) and (3,44)

$m=\frac{44-20}{3-0}=\frac{24}{3}=8$

Then, we use the point-slope formula, with the slope we found and the point (0,20)

$y-y_{1} =m(x-x_{1} )\\y-20=8(x-0)\\y=8x+20$

Therefore, the right answer is B.
