what is the slope of the line that passes through the points (9, 4) and (3, 9)? write your answer in simplest form.
Answer
Explanation:
Step1: Recall slope formula
The slope $m$ of a line passing through 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 $(x_1,y_1)=(9,4)$ and $(x_2,y_2)=(3,9)$.
Step3: Substitute values into formula
$m=\frac{9 - 4}{3 - 9}=\frac{5}{-6}=-\frac{5}{6}$
Answer:
$-\frac{5}{6}$
