The Point A and B are (k,2) and (-2,L)respectively Co ordinate point (-1,1) In the mid point of AB find the value of k and L.
The Point A and B are (k,2) and (-2,L)respectively Co ordinate point (-1,1) In the mid point of AB find the value of k and L.
x coordinate of midpoint is
(k -2)/2 = -1
y coordinate of midpoint is
(2+ L)/2 = 1
k -2 = -2
k = 0
2 + L = 2
L = 0
Origin
K=L=0
(xa+xb)/2=-1
(k-2)=-2
k-2=-2
k=0
(ya+yb)/2=1
2+L=2
L=2-2
L=0
K=0
L=0
k=2*(-1)+2=0✓
L=2*1-2=0✓
Please help me guys
k= 0, and L = -1
mid point= (X1+X2/2 , Y1+Y2/2)= (k-2/2=-1 and L+2/2 = 1 ) ==k-2 =-2 and L+2= 2 therefore k= 0 and L =0……..(0, 0) at the origin.
{(k-2)/2}=-1>>>>k-2=-2 and so k=-2+2=0, also {(L+2)/2}=1>>>>L+2=2 and so L=2-2=0 so that K=L=0
