Answer:
Step-by-step explanation:
We are asked to find the midpoint of a line segment. The midpoint bisects the line segment, or divides it into 2 equal parts. We find the midpoint by finding the average of the x-coordinates, then the y-coordinates.
The endpoints are (-9, 3) and (7, -8). Match the value and the corresponding variable.
- x₁= -9
- y₁ = 3
- x₂ = 7
- y₂ = -8
Substitute the values into the formula.
Solve the numerators.
- -9+7 = -2
- 3+ -8 = -5
Divide.
The fraction can be written as a decimal.
The midpoint of the line segment is (-1, -5/2) or (-1, -2.5)
