Question

A student drew the following line as their line of best fit in our Desmos activity from today.

Do you think this student drew the line of best fit for the data represented by green dots? Why or why not? What makes a good line of best fit?

Use 3-4 complete sentences to explain your thoughts below.

Answer 1

Answer and step-by-step explanation:

No, this is not a good line of best fit.

A good line of best fit should be centered in the data, hitting as many points as possible. About half of the points should be above the line and about half of the points should be below the line.

In this graph, only two points are below the line, and the other 4 are above it. This means it is too low.

Answer 2

The line of best fit would be slightly higher due to the amount of green above the line in this representation is higher than that of below
