Answer:
True: If you add 6 to a, this will be greater than b.
Step-by-step explanation:
If the ordered pair (a,b) satisfies the inequality y < x + 6, then the coordinates of this point satisfy the inequality. Substitute into the inequality x = a and y =b:

Check all options:
A. Subtract 6 from b:

So, if you subtract 6 from b it will be less than a but never equal to a, so this option is false.
B.

So, a is greater than b - 6, not b. This option is false.
C. If you add 6 to a, then

This option is true.
D. a+6 is greater than b, so it cannot be less than b. This option is false.
