@horsegirl27 can you help?

OpenStudy (horsegirl27):

OpenStudy (horsegirl27):

Ok you can see that y is x going up by 3 each time

OpenStudy (horsegirl27):

So what do you think it is?

OpenStudy (anonymous):

B

OpenStudy (anonymous):

no C put in x values and see it matches the y value x=o 0+3=3 etc

OpenStudy (horsegirl27):

no

OpenStudy (horsegirl27):

As I said, x is going up by 3 each time. So it has to be y=x+3 like I said. So yes, C

OpenStudy (anonymous):
