This is the answer of question 2
Answer:
Step-by-step explanation:
question no : 1 answer is option ( d ) ( 4, -1 )
using section formula ,
A ( x, y ) = [ m1x2 + m2x1 / m1 + m2 , m1y2 + m2y1 / m1 + m2 ]
=[ 2 × 2 + 1×8 / 2 +1 , 2 × 3 + 1 × -9 / 2+ 1]
= [ 4+ 8 /3 , 6 -9 /3 ]
= [ 12 / 3 , -3 / 3]
= [ 4, -1 ]
question no : 2 answer is option (c) 6
question no : 3 answer is option (b) -4
explanation for : Q 3
By using mid point formula ,
A(m , 5 ) = [-6 +( -2) / 2 ; 7 + 3/ 2]
=[ -8/2 ; 10/ 2]
= [-4 , 5 ]
thus we can say that m belongs to x -axis
therefore : m = -4
