Answer

Answer:

C. negative

Explanation:

Step1: Recall slope concept

Slope is $\frac{\text{change in }y}{\text{change in }x}$.

Step2: Identify variables

Let $x$ be cards sold, $y$ be remainder of goal.

Step3: Check change

As $x$ (cards sold) increases (from 10 to 20 etc.), $y$ (remainder of goal) decreases (from 875 to 795 etc.).

Step4: Determine slope sign

Since $y$ decreases as $x$ increases, slope is negative.
