x-value, highlight any x-value and enter the desired
value.
To display the corresponding y-value when

8. Press q(ax +b) for slope-intercept form of a
line. Substitute the a- and b-values displayed
into the given formula.
When the correlation coefficient, r, equals 1,
you have a perfect regression.
