Question

Find an equation for the line of beat fit.Use the points (20, 1.2) and (53, 2.6)

Answer 1

`y=(1.4)/(33) x +(11.6)/(33)`

Explanation:

the slope:

`m=(2.6-1.2)/(53-20) =(1.4)/(33)`

The equation:

`y-1.2=(1.4)/(33) (x-20)`

`y=(1.4)/(33) x-(28)/(33) +1.2`

`y=(1.4)/(33) x-(28)/(33) +(39.6)/(33)`

`y=(1.4)/(33) x+(11.6)/(33)`

Hope this helps
