Chapter 5.1, Problem 5P

Find the slope of each line.

To determine

To calculate: slope of the line

Answer to Problem 5P

The slope of the line is 3

Explanation of Solution

Given information:

  

The two points from the graph are $A\left(1,2\right)$ and $B\left(0,-1\right)$

Calculation:

The slope of the line when two points on the line are given i.e. $A\left(x_1,y_1\right)$ and $B\left(x_2,y_2\right)$

  $slope=\frac{y_2-y_1}{x_2-x_1}$

The two points from the graph are $A\left(1,2\right)$ and $B\left(0,-1\right)$ , then slope is:

  $\begin{array}{l}slope=\frac{-1-2}{0-1}\\ slope=\frac{-3}{-1}\\ \boxed{slope=3}\end{array}$
