A) 3x ? 2y + 5
B) 3x ? 2y + 10
C) 2x + 3y ? 5
D) 6x ? 4y ? 7
Correct Answer: A
Solution :
The midpoint of \[P(-2,\,6)\] and \[Q(4,\,2)\] is \[\left( \frac{-2+4}{2},\,\frac{6+2}{2} \right)\] i.e., \[(1,\,4)\] and the gradient of line \[PQ=\frac{2-6}{4+2}=\frac{-2}{3}\] \ The slope of \[L=\frac{3}{2}\] Hence the equation of line which passes through point \[(1,\,4)\] is \[y-4=\frac{3}{2}(x-1)\] Þ \[3x-2y+5=0\] .You need to login to perform this action.
