Which equation represents the perpendicular bisector of the given line segment?
In-s [12.5K]

Answer:

Option D. x=10

Step-by-step explanation:

step 1

Find the midpoint of the given line segment

we know that

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

we have

A(5,10),B(15,10)

substitute the values

M=(\frac{5+15}{2},\frac{10+10}{2})

M=(10,10)

step 2

Find the equation of the perpendicular bisector

we know that

The equation of a perpendicular bisector is equal to the x-coordinate of the midpoint, because is a vertical line (parallel to the y-axis)

therefore

the equation is equal to

x=10
