Answer:
2.5
Step-by-step explanation:
The formula to find the midpoint of a line segment: [tex](\frac{1}{2}x_{1} + \frac{1}{2}x_{2}, \frac{1}{2}y_{1} + \frac{1}{2}y_{2})[/tex]
Where:
[tex]x_{1} = -5\\x_{2} = 10\\y_{1} = 9\\y_{2} = 8[/tex]
1) Substitute the values into the midpoint formula.
[tex](\frac{1}{2}*-5 + \frac{1}{2}*10, \frac{1}{2}*9 + \frac{1}{2}*8)[/tex]
2) Solve it.
= [tex](-2.5 + 5, 4.5 + 4)[/tex]
= (2.5, 8.5)
