Chapter 3: Q.539 (page 364)

Find the slope of each line shown.

(a)

(b)

Short Answer

Expert verified

(a) The slope of the line is -35.

(b) The slope of the line is undefined.

Step by step solution

01

Step 1. Formulas/Definitions

The formula to find the slope between two pointsx1,y1,x2,y2is

m=y2-y1x2-x1.

The slope of a vertical line is undefined and the slope of the horizontal line is 0.

02

Step 2. Part (a)-Explanation

From the given graph, two points that lie on the line are x1,y1=-5,2,x2,y2=0,-1.

Find the slope.

m=-1-20--5m=-35

The slope is-35.

03

Step 3. Part(b)-Explanation

The given graph of the line is a vertical line.

So, the slope of the vertical line is undefined.
