Chapter 1: Q 7. (page 51)

Use P1=-1,3and P2=5,-1.

(a) Find the slope of the line containingP1andP2.

(b) Interpret this slope.

Short Answer

Expert verified

(a)The slope of the line containing P1and P2is 0.

(b) Interpretation of slope is shown below.

Step by step solution

01

Step 1. Given information.

Consider the given pointsP1andP2.

02

Step 2. (a) Formula used.

The formula used to find slope is m=y2-y1x2-x1.

Substitute the value of x1,x2and y1,y2.

m=-1+15+1m=0

03

Step 3. (b) Plot the graph.

The graph for the slope m=0shown below.
