Chapter 13: Q. 5 (page 532)

Find the slope of the line through the points named. If the slope is not defined, write not defined.
(1, 2); (-2, 5)

Short Answer

Expert verified

The slope of the line is -1.

Step by step solution

Step-1 – Given

The given points are (1, 2); (-2, 5).

Step-2 – To determine

We have to find the slope of the line through the points (1, 2); (-2, 5).

Step-3 – Calculation

We compare (1, 2); (-2, -5) with $(x_{1}, y_{1}); (x_{2}, y_{2})$ .

here,

$\begin{array}{l} x_{1} = 1 \\ y_{1} = 2 \\ x_{2} = - 2 \\ y_{2} = 5 \end{array}$

So, $s l o p e (m) = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{5 - 2}{- 2 - 1} = - 1$

It means, the slope of the line is -1.
