Chapter 9.4, Problem 22CCR

To determine

To determine the slope of the line passes through each pair of points.

Answer to Problem 22CCR

Slope of line passing through each pair of points is $\infty$ .

Explanation of Solution

Given information:

Two points are $A\left(-2,3\right)\text{}\text{ and }B\left(-2,8\right)$

Calculation:

The slope of the line passes through each pair of points.

Points are $A\left(-2,3\right)\text{}\text{ and }B\left(-2,8\right)$

  $\begin{array}{l}\text{slope}=\frac{\text{change}\text{in}y\text{unit}}{\text{change}\text{in}x\text{unit}}\\ m=\frac{y_2-y_1}{x_2-x_1}\\ m=\frac{8-3}{(-2)-(-2)}\\ m=\frac{5}{-2+2}\\ m=\frac{5}{0}\\ m=\infty \end{array}$

Therefore,

The slope of line passing through the given points is $\infty$ .
