Question

find the slope of the line that passes through (4, 8) and (8, 7). simplify your answer and write it as a proper fraction, improper fraction, or integer.

Explanation:

Step1: Recall slope formula

The slope $m$ between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2-y_1}{x_2-x_1}$

Step2: Assign values to variables

Let $(x_1,y_1)=(4,8)$ and $(x_2,y_2)=(8,7)$. Substitute into formula:
$m=\frac{7-8}{8-4}$

Step3: Calculate numerator and denominator

$m=\frac{-1}{4}$

Answer:

$\frac{-1}{4}$
