Question

I need the answers with a explanation how you got it

Answer 1

In the question, we are given the table of values below.

Using the graph plotter,

The slope(m) and the intercept(c) is given as (nearest tenth)

$m=14.0\text{ and c =}478.7$

This can be inserted into the equation of best fit below

$y=14.0x+478.7$

Also, the correlation coefficient is given as

$r=1.0$

The relationship is also strong and positive
