anonymous · Answer

To solve this, you have to take each set of ordered pairs and plug them into the equation

how?

anonymous · Answer

So if we were to see if A is the right choice, plug in all the pairs of numbers. So the first would be 0 for x and 3 for y and then solve the equation etc etc

Do you guys need help?

spring98 · Answer

yes we do plz!!

gabebae · Answer

it's 	A.  {(0, 3), (1, 6), (2, 9)}

gabebae · Answer

Do you need me to explain it?

spring98 · Answer

sure that is what i was just going to say!!

gabebae · Answer

All you're basically doing is taking the x and y coordinates and substituting them into the equation y – 3 = 3x.
