what is the slope of the line that passes through the points (3, -3) and (18, -3)? write your answer in simplest form.
Answer
Explanation:
Step1: Recall slope - formula
The slope formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2 - y_1}{x_2 - x_1}$.
Step2: Identify the points
Let $(x_1,y_1)=(3,-3)$ and $(x_2,y_2)=(18,-3)$.
Step3: Substitute values into formula
$m=\frac{-3-(-3)}{18 - 3}=\frac{-3 + 3}{18 - 3}$.
Step4: Simplify the expression
$\frac{-3 + 3}{18 - 3}=\frac{0}{15}=0$.
Answer:
$0$
