Question

What is the equation of this graph/line in y=mx+b form?

Answer 1

`y=1.0238x-0.6548`

See the explanation

Explanation:

If you rank in order of sleep time there is a loose association that appears to follow a straight line (with a degree of variation)

Letting Excel derive it for me we have:

`y=1.0238x-0.6548`

Where `y` is hours of sleep and `x` is the score.

There is a way to actually calculate this using calculus and I covered it at university but do not wish to go that deep.
