A graph includes the ordered pair (2,4). Write two different rules that would be possible for this graph. Explain how you found your answer.

So it is in (x, y) format so

2=x and 4=y so

4 = something 2

4=2 times 2 so one equation is

4=2x

y=2x

4=2+2

so another equation would be y=x+2

2 possible equations are

y=2x or

y=x+2
