You can put this solution on YOUR website! If x is directly proportional to y, then we can say that whenever x increases y increases. That also goes for when x decreases, then y decreases. A good example is:
x is equal to the number of hours you work everyday
y is equal to the number of dollars you earn everyday
If you work more hours, then you'll get more income.
I hope this helped you. :]
You can put this solution on YOUR website! "algebra proportions' seems a likely category.
Repeating what the other tutor said
if you work 8 hours for 10 dollars you will get 80 dollars
80=8*10
p=10*h
pay = wage*hours
y=kx
Usually in those direct proportion problem you will be given a sample x and y
so you can find k
then they will either given you n x or y and want the other
John worked 8 hours and earned $64
the next day he earned $72
how many hours did he work the second day
inversely proportional
y=k/x
but that is another topic
