Chapter 1: Q. 18 (page 40)

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

Short Answer

Expert verified

The slope of the line is $\frac{2}{3}$ and the graph is

Step by step solution

01

Step 1. Given Information

The given points are $(- 1, 1); (2, 3)$

02

Step 2. Calculation

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

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

03

Step 3. Graph

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