Question

The line joining the points (2,-1); (5,-6) is bisected at P. If P lies on 2x+4y+k=0 find the value of k.

Answer 1

Answer:

Hey Ben, It's just very very simple.......

Step-by-step explanation:

Bisection point/mid-point P of (2,-1) and (5,-6):

You get it as (7/2,-7/2) by applying mid-point formula.....

So Substitute (7/2,-7/2) in 2x+4y+k=0 as that point lies in that equation......

Then by solving you get k value as 7.....

Alright!!!!!!
