On your math quiz, you earn $5$ points for each question that you answer correctly. In the table below, $x$ represents the number of questions that you answer correctly on your math quiz, and $y$ represents the total number of points that you score on your quiz.
The relationship between these two variables can be expressed by the following equation:
$y=5x$.
Suppose you scored $75$ points total on your math quiz.
