Question

For every hour that Noah studies, his test score goes up 3 points. Explain which is the independent variable and which is the dependent variable. Write an equation modeling the relationship between hours studied h and the increase in Noah's test score s.

Answer 1

The independent variable is the test hours that he studies; because they are not affected by any of the other variables. The dependent variable is the test score; because the amount of the test score depends on the variable of the studied hours. 

t=test score
h=hours studied
 
t+h3

Not sure about the equation though. Might wanna check that. Hope this helps!

Answer 2

The independent variable is hours and the score or points is the dependent variable .equation is s=3h
