Trisecting Line Segments and Coordinates

The video tutorial explains how to find points that trisect a line segment with given endpoints. It involves calculating changes in x and y coordinates, dividing these changes by three, and determining the ordered pairs for the trisection points. The process is verified by ensuring the calculated points create three equal segments.

What are the endpoints of the line segment that needs to be trisected?

• (-6, 3) and (3, -9)

• (-3, 6) and (9, -3)

• (6, -3) and (-3, 9)

• (3, -6) and (-9, 3)

What does it mean to trisect a line segment?

• Divide it into two equal parts

• Divide it into three equal parts

• Divide it into four equal parts

• Divide it into five equal parts

What is the change in x-coordinate from point A to point B?

• 15

• 6

• 12

• 9

What is the change in y-coordinate from point A to point B?

• -3

• -12

• -6

• -9

How do you find the change in x for each segment when trisecting?

• Multiply the total change in x by 3

• Divide the total change in x by 3

• Add 3 to the total change in x

• Divide the total change in x by 2

What is the change in y for each segment when trisecting?

• -3

• -12

• -6

• -9
