Question

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.

Answer 1

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
