Chapter 2: Q21. (page 105)

Find the slope of the line that passes through each pair of points
$鈥� 鈥� (- 2, 5), (4, 5)$

Short Answer

Expert verified

The Slope of the line that passes through the points $(- 2, 5), (4, 5)$ is 0.

Step by step solution

Step-1 – Apply the concept of slope

The slope of a line is the ratio of the change in the y-coordinates to the change in the x- coordinates.

Symbolically, the slope m of the line passing through the points $(x_{1}, y_{1}) and (x_{2}, y_{2})$ is given by $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ where $x_{1} 鈮� x_{2}$ .

Step-2 – Example of a slope through two points

Suppose a line passes through the points $(2, 4), (3, 0)$ . Then the slope of the line passing through these points is given by

$\begin{matrix} m = \frac{0 鈭� 4}{3 鈭� 2} \\ = \frac{鈭� 4}{1} \\ = 鈭� 4 \end{matrix}$

Step-3 – Calculate the slope of the given points

The given points are $(- 2, 5) and (4, 5)$ . Therefore, $x_{1} = - 2; x_{2} = 4; y_{1} = 5; y_{2} = 5$ .

Hence the slope of the line through these points is calculated as

$\begin{matrix} m = \frac{5 鈭� 5}{4 鈭� (鈭� 2)} \\ = \frac{0}{4 + 2} \\ = \frac{0}{6} \\ = 0 \end{matrix}$
