Chapter 10: Q 1. (page 643)

1. The formula for the distance d from P1=(x1,y1)toP2=(x2,y2)is d = _____.

Short Answer

Expert verified

The formula for the distance d fromP1=(x1,y1)toP2=(x2,y2)is,d=(x2-x1)2+(y2-y1)2

Step by step solution

01

Step 1. Given information.

We have given two points P1=(x1,y1)andP2=(x2,y2).

02

Step 2. Concept.

Distance between two points is the length of the line segment that connects the two given points.

03

Step 3. Explanation.

Distance between the points, P1=(x1,y1)andP2=(x2,y2)is,

d=(x2-x1)2+(y2-y1)2

04

Step 4. Conclusion

Hence, distance from the pointsP1=(x1,y1)toP2=(x2,y2) is,d=(x2-x1)2+(y2-y1)2
