Answer:

8.) yes it is a solution because if plug in 7 for x and 16 for y you get 16=7+9 which equals 16

9.) No it is not a solutions because if you plug in 28 for y and 5 for x you 28=2(5)+8 and then when you multiply the 2 and the 5 you get 28=10+8 and 10+8 equals 18 and 28 and 18 are not equal

I hope this helped! :)))

Answer:

8) the ordered pair is a solution, 9) the ordered pair is not a solution

Explanation:

8) if you plug in the values of x into the equation, which is 7, 7+9 equals to 16, which is the y value in the ordered pair

9) the same is for this question, if you plug in the x value into the equation, which is 5, 2(5)+8 is equal to 10+8 which is equal to 18. This isn't equal to the y value in the ordered pair
