Creating and Graphing Two Variable Equations Practice Test

A small ball is thrown upward from a platform. Its height (in meters) after $t$ seconds is modeled by $h = -4.9t^2 + 12t + 1$. Graphing is needed for $0 \le t \le 3$. Which option gives the correct equation and appropriate axes labels and a reasonable scale?

A streaming service charges $\$9$ per month plus $$2$ per movie rented. Let $m$ be the number of months, $n$ be the number of movies, and $C$ be total cost in dollars. Create an equation representing the total cost in terms of $m$ and $n$.
