Q. 19 - Precalculus Enhanced with Graphing Utilities

Question

Plot each pair of points and determine the slope of the line containing them. Graph the line by hand.  

$(-3,-1);(2,-1)$

Step-by-Step Solution

Answer

The slope of the line is 0 and the graph is 

Step 1. Given Information

The given points are $(-3,-1);(2,-1)$

Step 2. Calculation

Use the slope formula to find the slope of the line between the given points.

$$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ =\frac{-1-(-1)}{2-(-3)} \\ =\frac{-1+1}{2+3} \\ =0 \end{gathered}$$

Step 3. Graph

The line is graphed by drawing a line passing through the points.
