Question

Which line is the best-fit line for the given data? line 1 line 2 line 3 line 4

Answer 1

Line 3 as it goes between most of the marks and near all of them!

Answer 2

Answer:

Line 3

Step-by-step explanation:

Observe each line and keep in mind all points.

Line 1 is wrong because it goes over each and every point.

Line 2 is wrong because it ignores the leftmost point and rightmost point.

Line 4 is wrong because it goes under each and every point.

This leaves Line 3 as good by default. It goes over as many points as it goes under and doesn't ignore any points.
