DOES THE ANSWER HELP YOU?
The answer is D because The ordered pairs graphed are (2,3), (6,9), and (8,12). They all have a ratio of 2 to 3. Which means each point is 2 larger on the x-axis and 3 larger on the y-axis than the previous point. The point that is missing is (4,6) since 2 + 2 = 4 and 3 + 3 = 6.
You plug in x for 3 so it would be 10(3) + 2, and 10 times 3 is 30 and 30 plus 2 is 32
