Question

p(x,6) is the midpoint of seg AB with A(6,5) and B(4,y) then y=?​

Answer 1

Answer:

y = 7

Step-by-step explanation:

Given,

p(x, 6) is mid point A(6, 5) and B(4, y).

Using mid point formula,

(x, y) = [(x1 + x2)/2 , (y1 + y2)/2]

(x, 6) = [(6 + 4)/2 , (5 + y)/2]

(x, 6) = [10/2, (5 + y)/2]

(x, 6) = (5, (5+y)/2)

Comparing corresponding coordinates,

6 = (5 + y)/2

12 = 5 + y

12 - 5 = y

7 = y

So required value of y is 7.

Answer 2

Step-by-step explanation:

P(x,6) is (x,y), A(6,5) is (X1,Y1), B(4,y) is (X2,Y2)

By midpoint formula

X=X1+X2÷2 & Y=Y1+Y2÷2

put value

X=6+4÷2 & 6=5+Y÷2

X=10÷2 & 6×2=5+Y

X =5. & 12=5+Y =12-5=Y =7
