Answer
a) I would expect the solution to be of the form $y < c$.
b) 1.75 = y (estimate)
c) $y < \frac{22}{13}$
Work Step by Step
a) Since the table value changed from true to false for a value of 2, 2 would be deemed not a number in the solution set. (Thus, y>2 would not work.)
b) This is just an estimate. Since the inequality moves from true to false with a value of 2, I would estimate the value where the inequality moves from true to false is halfway between 1.5 and 2.
c)
The estimate was a bit too high, as y < 1.692.
$7y + 2 < 6 (4-y)$
$7y + 2 < 24 - 6y$
$7y + 2 (-2) < 24 (-2) - 6y$
$7y < 22 - 6y$
$7y (+6y)< 22 - 6y (+6y)$
$13y < 22 $
$y < \frac{22}{13}$
