Final answer:
The point (1,9) does not satisfy the inequality y ≤ x + 7.
Step-by-step explanation:
To determine if the point (1,9) satisfies the inequality y ≤ x + 7, we substitute the x and y values into the inequality and check if it is true.
Plugging in the values, we get 9 ≤ 1 + 7, which simplifies to 9 ≤ 8. Since this inequality is false, the point (1,9) does not satisfy the inequality y ≤ x + 7.
