A linear function H models a relationship in which the dependent variable increases one unit for every five units the independent variable decreases the value of the function at 0 is 3

Question

Slope

Answer 1

If the function is 0 at 3, you are saying f(3) = 0. or you have the point (3, 0).

x is the independent variable, and y is the dependent variable.

If the dependent variable increases one unit for every five units the independent variable decreases 

then you will also have a point at ( -2, 1). If this is a linear function, you can find the equation given those 2 points.
