Chapter 3.3, Problem 18PPS

To determine

To find the slope of each point

Answer to Problem 18PPS

Value of slope is $m=\frac{0}{-5}$

Explanation of Solution

Given information:

  $C(3,1),D(-2,1)$ .

Formulaused:

  $m=\frac{y_2^{}-y_1^{}}{x_2^{}-x_1^{}}$

Where, $m$ is slope and $y_2^{}-y_1^{}$ are difference in y coordinates and $x_2^{}-x_1^{}$ difference in x coordinates.

Calculation:

Coordinates are:

  $C(3,1),D(-2,1)$

So,

Let $x_1^{}=3,x_2^{}=-2$ and,

  $y_1^{}=1,y_2^{}=1$

Substituting value in formula,

$m=\frac{1-1}{-2-3}$

Solving,

$m=\frac{0}{-5}$

Hence, value of slope is $m=\frac{0}{-5}$ .
