Chapter 3: Q.420R (page 355)

In the following exercises, find the slope of each line shown,

Short Answer

Expert verified

Slope of given line is13.

Step by step solution

01

Given information.

The graph showing line:

02

Find two points on the line.

Write two points from the graph through which the line is passing whose coordinates should be integer.

From the graph, such two points are: 2,-2and5,-1.

03

Find the slope.

Slope of line passing through two points x1,y1and x2,y2is given by:

m=y2-y1x2-x1

Here, we have: x1,y1=(2,-2);x2,y2=(5,-1)

So, required slope is :

m=-1-(-2)5-2=-1+23=13
