Graph each inequality. ? 1.? ? SOLUTION:?? The boundary of the graph is the graph of y = 4. Since the inequality symbol is , the boundary line is solid. ? y is less than 4, so the region less than 4 is shaded. ? ? ANSWER:?? ? 2.? ? SOLUTION:?? The boundary of the graph is the graph of x = ?6.?Since?the?inequality?symbol?is??,?the?boundary?line?is?solid. x is greater than or equal to ?6, so the region greater than ?6 is shaded. ? ? ANSWER:?? ? 3.? ? SOLUTION:?? The boundary of the graph is the graph of x + 4y ?=?2.?Since?the?inequality?symbol?is??,?the?boundary?line?is?solid. ? Test the point (0, 0). ? ? The region that contains (0, 0) is shaded. ? ? ANSWER:?? ? 4.? ? SOLUTION:??
