Short Answer

Plot each pair of points and determine the slope of the line containing them. Graph the line by hand.
$(- 3, - 1); (2, - 1)$

The slope of the line is 0 and the graph is

TABLE OF CONTENTS

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.

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{- 1 - (- 1)}{2 - (- 3)} = \frac{- 1 + 1}{2 + 3} = 0$

Step 3. Graph

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