Chapter 4: Q. 257 (page 494)

In the following exercises, use the slope formula to find the slope of the line between each pair of points.
$(- 3, 3), (4, - 5)$

Short Answer

Expert verified

The slope of the line is $\begin{array}{rcl} \frac{- 8}{7} \end{array}$ .

Step by step solution

Step 1. Given information

The given coordinates are $(- 3, 3), (4, - 5)$ .

Step 2. Determine the slope

Substitute $x_{1} = - 3, y_{1} = 3, x_{2} = 4, y_{2} = - 5$ into the slope formula $m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ .

$\begin{array}{rcl} m & = & \frac{- 5 - 3}{4 - (- 3)} \\ = & \frac{- 8}{4 + 3} \\ = & \frac{- 8}{7} \end{array}$

So, the slope of the line is $\begin{array}{rcl} \frac{- 8}{7} \end{array}$ .
