Question

if the mid point of line segment joining the points p(6,b-2) and Q(-2,4) is (2,-3) fimd the value of b

Answer 1

Since the three points lie on the same line and two points are known, we can use their gradient to get the unknown. The gradient is the same.

Using points (-2,4)and(2,-3)

We get the gradient as :

(2,-3)-(-2,4)=cbange in your /change in x=-7/4

Getting the gradient using the point with unknown and one known point we get:

(2,-3)-(6,b-2)=change in y/change in x=(-1-b)/-4=-7/4=(1+b)/4=-7/4

4+4b=-28

4b=-32

b=-8

Answer 2

-8
