Exercise 30 Page 557

Find the segment connecting A and B that has the shortest distance between them.

C(9,0)

Practice makes perfect

Let's begin by plotting the two given points.

Point C will be the point where the segment connecting points A and B intersects the x-axis.

Note that AB has the shortest distance between A and B. Therefore, if C has the coordinates (9,0), the distance AC+BC is minimized.
