Question

use the slope formula to determine the slope of the line containing the two points. express numbers as integers or simplified fractions. select \undefined\ if applicable. (1, 5) and (1, 8) the slope is

Explanation:

Step1: Recall slope formula

The slope formula between two points $(x_1,y_1)$ and $(x_2,y_2)$ is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $(x_1,y_1)=(1,5)$ and $(x_2,y_2)=(1,8)$.

Step2: Substitute values

Substitute the values into the formula: $m=\frac{8 - 5}{1 - 1}=\frac{3}{0}$.

Answer:

Undefined
