Finding the Second Endpoint of a Segment (3.2.2)

Question 1

• Any point’s location is given by the ordered pair (x,y) where x measures horizontal distance from the origin and y measures vertical distance from the origin.

Answer 1

• Any point’s location is given by the ordered pair (x,y) where x measures horizontal distance from the origin and y measures vertical distance from the origin.

Question 2

If you are given an endpoint and a midpoint, you set up a
generic point for the second end. Label this point as (x1
,y1
).
It always helps to sketch a graph so you can visually
understand the situation you are working with.
Now use the midpoint formula. Substitute in your values
and solve for the missing x and y.
Once you find the missing x and y, you can set the ordered
pair for the endpoint and graph it.
