Chapter 3: Q. 92 (page 275)

Use the slope formula to find the slope of the line between each pair of points.
$(3, - 6), (2, - 2)$ .

Short Answer

Expert verified

Slope of the line is $- 4$ .

Step by step solution

01

Step 1. Given information

Given points are $(3, - 6), (2, - 2)$ .

02

Step 2. Finding the Slope.

Here $(x_{1}, y_{1}) = (3, - 6)$ and $(x_{2}, y_{2}) = (2, - 2)$ .

By using slope formula, we have

$\begin{array}{rcl} m & = & \frac{y_{2} - y_{1}}{x_{2} - x_{1}} \\ = & \frac{- 2 - (- 6)}{2 - 3} \\ = & \frac{4}{- 1} \\ = & - 4 \end{array}$

Therefore slope of the line is $- 4$ .
