To determine if the point (5,7) is a valid solution to the inequality y > -2x + 9, substitute the values x = 5 and y = 7 into the inequality and check if the inequality is satisfied.
The given inequality is:
y > -2x + 9.
Substituting x = 5 and y = 7:
7 > -2(5) + 9.
Simplifying:
7 > -10 + 9,
7 > -1.
Since 7 is greater than -1, the inequality y > -2x + 9 is satisfied for the point (5,7).
Therefore, (5,7) is a valid solution to the inequality.
