Answer:
D
Explanation:
Substitute the x and y values of each answer option. If y is greater than or equal to half of x plus 10, the answer is correct.
In the last option, if you substitute the x value, -2, into 1/2x + 10, the result is 9. The y value is 11, which is greater than or equal to 9, so the last one is the correct answer.
