Chapter 3: Q. 418R (page 355)

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

Short Answer

Expert verified

Slope of given line is -3.

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:0,0and-1,3

03

Find the slope.

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

localid="1645581330898" role="math" m=y2-y1x2-x1

Here, we have localid="1645581350909" role="math" x1,y1=(0,0);x2,y2=(-1,3)

So, required slope is:

localid="1645581402276" role="math" m=3-0-1-0=-3
