Question

If the midpoint of the line segment joining the points p (6,b-2) and Q (-2,4) is (2,3) find the value of b.​

Answer 1

Answer:

b=4

Step-by-step explanation:

1. equation of straight line :- (y-y1)/(y2-y1)=(x-x1)/(x2-x1)

2. (-2,4)&(2,3) belong to the same line

3. (y-4)/(3-4)=(x+2)/(2+2)

4. (4-y)*4=(x+2)

5. Since (6,b-2) belong to the same line it should satisfy the above equation.

6. (6-b)*4=8

7. b=6-2=4
