Question

mid point of the line joining the points (x,3) and (3,4) is(2,7/2) then x is​

Answer 1

$\frac{3 + k}{2} = 2$

⇒3+k=2x -------(1)

$\frac{4 + 7}{2 } = y$

--------------------(2)

$y = \frac{11}{2}$

given that, k passes through the line 2x+2y+1=0

[From (1)] and (2)]

⇒3+k+11+1=0

⇒k+15=0

⇒k=−15
