O yupper! Andras is coming! Woo Hoo!

anonymous · Answer

for A it does. As the rate of change is constant. So if you change x by one y changes by 6.
equation for it: y=x+6

for B it is not as the rate of change is not constant. So changing x from 0 to 1 y changes 2
but if you change x from 2 to 3 y changes 8
