Question

A calculator was used to perform a linear regression on the values in the

table. The results are shown to the right of the table
LinReg
y = ax+b
a=-2.9
b=13.5
r2 =.9688940092
r=-.9843241383
What is the line of best fit?

Answer 1

y = -2.9x + 13.5

Explanation:

Answer 2

`y=-2.9x+13.5`

Explanation:

Linear Regression: Best Fit

It's the equation of a line that approaches the best to a set of data points, tipically obtained from measures of some physical reality. It's computed by using the least squares method.

The calculator outputs

y = ax+b

a=-2.9

b=13.5

r2 =.9688940092

r=-.9843241383

The values of a and b need to be replaced in the equation to complete the line of best fit

`\boxed{ y=-2.9x+13.5}`
