Practice: Determining Whether an Ordered Pair is a Solution to y>2x+3y > 2x + 3

To determine whether the ordered pair (3,12)(3, \frac{1}{2}) is a solution to the linear inequality y>2x+3y > 2x + 3, substitute the xx and yy coordinates into the inequality. Replacing xx with 33 and yy with 12\frac{1}{2} yields 12>2(3)+3\frac{1}{2} > 2(3) + 3, which simplifies to 12>6+3\frac{1}{2} > 6 + 3, or 12>9\frac{1}{2} > 9. Because this results in a false mathematical statement, the ordered pair (3,12)(3, \frac{1}{2}) is not a solution to the inequality.
