Answer 1

Make sure you line up your X and Y values.
\[(0,68) (10,84) (15, 107) (20,110) (30, 125)\]
Then on a calculator, you'll go to STAT enter

Then you will type in your X and Y values

Once you type in your X and Y values, go back to STAT, move over to CALC scroll down to number 4 (LinReg)

Then you'll press enter and go all the way to Calculate then hit enter again

You should get

\[y=ax+b\]

\[a=1.97\]
