Chapter 4: Q. 261 (page 494)

In the following exercises, use the slope formula to find the slope of the line between each pair of points.
$(4, - 5), (1, - 2)$

Short Answer

Expert verified

The slope of the line is $- 1$ .

Step by step solution

Step 1. Given Information

The given coordinates are $(4, - 5), (1, - 2)$ .

Step 2. Determine the slope

Substitute $x_{1} = 4, y_{1} = - 5, x_{2} = 1, y_{2} = - 2$ into the slope formula, $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ .

$\begin{array}{rcl} m & = & \frac{- 2 - (- 5)}{1 - 4} \\ = & \frac{- 2 + 5}{- 3} \\ = & \frac{3}{- 3} \\ = & - 1 \end{array}$

So, the slope of the line is $- 1$ .
