Which equation could have been used to create this function table? x        y 1       10 2      11 5     14 10   19 15     24 (a) y = x + 9 (b) y = x + 10 (c) y = 9x (d) y = 10x

For multiple-choice questions, it is often faster to check the answers than to try to figure out what the answer should be.

Only selections (A) and (D) match the first entry in the table.
Of those, only selection (A) matches the second entry in the table.

The appropriate choice is ...
   (A) y = x + 9

The point (5, 10) will work for the rule y=x+5.y= 10 x= 510=5+510=10therefore the ordered pair (5, 10) works for the rule
