Chapter 1.3, Problem 20AYU

In Problems 17-24, plot each pair of points and determine the slope of the line containing them. Graph the line by hand.

$(4,2);(-5,2)$

To determine

To find: Plot the points $\left(4,2\right)$ and $\left(-5,2\right)$ and the slope of the line joining the point

Answer to Problem 20AYU

Solution:

slope $\text{<mi>m</mi> = 0}$

Explanation of Solution

Given:

The points $\left(4,2\right),\left(-5,2\right)$

Formula Used:

Slope $\text{<mi>m</mi> = }\frac{y_2-y_1}{x_2-x_1}$

Calculation:

The slope $m$ of the line containing the points $\left(4,2\right)$ and $\left(-5,2\right)$ is

$\text{<mi>m</mi> = }\frac{2-2}{-5-4}$

$=\frac{0}{-9}$

$=0$
