Answer: (-1, 1.5)
Note: 1.5 = 3/2
=======================================================
Step-by-step explanation:
The two points shown on the graph are located at (-3, -2) and (1, 5)
Let's focus on the x coordinates for now.
To find the midpoint of -3 and 1, we do two things in the order shown
- Add up the values: -3+1 = -2
- Divide in half: -2/2 = -1
Therefore, -1 is the midpoint of -3 and 1 on the number line.
It is also the x coordinate of the midpoint.
------------
Repeat these steps for the y coordinates of the given points.
- Add: -2+5 = 3
- Divide in half: 3/2 = 1.5
This is the y coordinate of the midpoint.
-------------
The midpoint overall is located at (-1, 1.5)
I used GeoGebra to confirm the answer as correct.
