Chapter 2: Q19. (page 72)

Find the slope of the line that passes through each pair of points.
$(7, 8), (1, 8)$

Short Answer

Expert verified

The slope of the line is $0$ .

Step by step solution

Step 1- Given information

A pair of points $(7, 8), (1, 8)$ .

Step 2- Formula used

The slope formula of a line is:

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Where, $m$ is slope of the line which is passes through the points $(x_{1}, y_{1}), (x_{2}, y_{2}) and x_{1} \neq x_{2} .$

Step 3- To find the slope

Here, $(x_{1}, y_{1}) = (7, 8) {and (x}_{2}, y_{2}) = (1, 8)$

So, $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

$\begin{array}{l} \Rightarrow m = \frac{8 - 8}{1 - 7} \\ \Rightarrow m = \frac{0}{- 6} \\ \Rightarrow m = 0 \end{array}$

Hence, the slope of the line is $0$ .
