Answer: (8, fraction 3/2)
Step-by-step explanation:
The formula for determining the midpoint of a line is expressed as
[(x1 + x2)/2 , (y1 + y2)/2]
Where
x2 represents final value of x on the horizontal axis
x1 represents initial value of x on the horizontal axis.
y2 represents final value of y on the vertical axis.
y1 represents initial value of y on the vertical axis.
From the information given,
x2 = 9
x1 = 7
y2 = - 1
y1 = 4
Therefore,
Midpoint = [(7 + 9)/2 , (4 - 1)/2]
Midpoint = (16/2, 3/2)
Midpoint = (8, 3/2)
