$\Rightarrow \text{G}(0,-3) = \Big(\frac{4+\text{ x}}{3},\frac{4+2+\text{ y}}{3}\Big)$
$\Rightarrow \frac{4+\text{ x}}{3} = 0 $ and $\frac{6 + \text{ y}}{3} = -3$
$\Rightarrow 4+\text{x} - 0 $ and $ 6+\text{ y} = -9$
$\Rightarrow \text{x} = -4 $ and$\text{ y} = -15$

In the given figure $P(5, -3)$ and $Q(3, y)$ are the points of teisection of the line segment joining $A(7, -2)$ and $B(1, -5)$. Then y equals:
- A
$2$
- B
$4$
- ✓
$-4$
- D
$\frac{-5}{2}$
AnswerSince $P$ and $Q$ are the points of trisection.
This means $AP = PQ = QB$.
So, $Q$ divides AB in the ratio $2 : 1$ and let the coordinates of $Q$ be $(x, y)$.
We know that, the centre is the mid-point of the diameter.
Using the section formula, we get
$(3,\text{y})=\Big(\frac{2(1)+1(7)}{2+1},\frac{2(-5)+1(-2)}{2+1}\Big)$
$\Rightarrow\ \text{y}=\frac{2(-5)+1(-2)}{2+1}$

If the coordinates of one end of a diameter of a circle are $(2, 3)$ and the coordinates of its centre are $(-2, 5),$ then the coordinates of the other end of the diameter are:
- ✓
$(-6, 7)$
- B
$(6, -7)$
- C
$(4, 2)$
- D
$(5, 3)$
AnswerCorrect option: A. $(-6, 7)$
Let the coordinates of the other end of the diameter be $(x, y)$.
We know that, the centre is the mid-point of the diameter.
Using the mid-point formula, we get:
$(-2,5)=\Big(\frac{2+\text{x}}{2},\frac{3+\text{y}}{2}\Big)$
$\Rightarrow\ \frac{2+\text{x}}{2}=-2$ and $\frac{3+\text{y}}{2}=5$
$\Rightarrow 2 + x = -4$ and $3 + y = 10$
$\Rightarrow x = -6$ and $y = 7$
So, the coordinates of the oyter end are $(-6, 7)$.

Let the coordinates of the point be $P(x, 0)$
Since the point lies on the $x$-axis. $P$ is equidistant from $A(7, 6)$ and $B(-3, 4)$
Using the distance from, we get
$ \mathrm{AP}^2=\mathrm{BP} $
$ \Rightarrow(7-\mathrm{x})^2+(6-0)^2=(-3-\mathrm{x})^2+(4-0)^2 $
$ \Rightarrow 49-14 \mathrm{x}+\mathrm{x}^2+36=9+6 \mathrm{x}+\mathrm{x}^2+16 $
$ \Rightarrow 85-14 \mathrm{x}=6 \mathrm{x}+25 $
$ \Rightarrow 20 \mathrm{x}=60 $
$ \Rightarrow \mathrm{x}=3$
Thus, the point $(3, 0).$
