hartnn · Answer

here, k1= 2, k2 = 3

hartnn · Answer

and you already know xA,yA,
xB,yB

xA= -4
yA = 6
xB= 5
yB=1

anonymous · Answer

Okay

hartnn · Answer

so what will u get for the x co-ordinate of the required point ?

hartnn · Answer

$\huge x_p = \dfrac{(5)2+ (-4)3}{2+3}$

anonymous · Answer

that was suppose to be the answer?? Lol

hartnn · Answer

simplify it
you'll get a value of x which is present in only once option

hartnn · Answer

**one option

anonymous · Answer

(-1,4.2)? Im not very good at simplify these

hartnn · Answer

nopes, you get x = -0.4
:)
