Chapter 1

Question 1

Midpoint Formula

Answer 1

Let A (x1,y1) and B (x2,y2) be points in a coordinate plane. The midpoint of AB (line segment above) is (x1+x2/2),(y1+y2/2).

Question 2

Distance Formula

Answer 2

Let A = (x1,y1) and B = (x2,y2) be points in a coordinate plane. The distance between A and B is… AB = square root (x2-x1)2 + (y2-y1)2.

Question 3

Midpoint

Answer 3

The point that divides the segment into 2 congruent segments.
