now try that for choice B and see if the values match
OpenStudy (anonymous):
y is 5 and x is 15 so 5=2(15
5=20?

actually that's x is 5 and y is 15. The first number in an ordered pair is always the x value and y is the second value
OpenStudy (anonymous):
Oh,
OpenStudy (anonymous):
so 15=2(5)
OpenStudy (anonymous):
don't forget the +5
OpenStudy (anonymous):
it's 15=2(5)+5
