Question

what type of slope is shown on the graph? a positive b negative c zero d undefined

Explanation:

Step1: Recall slope formula

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$.

Step2: Identify two points on line

Let's take two points on the given horizontal line, say $(-2,3)$ and $(2,3)$.

Step3: Calculate the slope

$m=\frac{3 - 3}{2-(-2)}=\frac{0}{4}=0$. A horizontal line has a zero - slope.

Answer:

C. Zero
