Question

Identify the graph of the following equation.

x < -3

Answer 1

The 1st Graph (A)

Explanation:

Test by substituting values for "x":

By substituting the numbers of 0 (0 < -3), -1 (-1 < -3), and -2 (-2 < -3), does that make the statement true?

The answer is FALSE. None of those values are satisfactory.

Therefore, by substituting -4 (-4 < -3), -5 (-5 < -3), and -6 (-6 < -3), these values are satisfactory and makes the statement true.
