- 1. Multiple Choice3 minutes1 ptFind the co-ordinates of the point which divides the line segment joining the points (6,3) and (-4,5) in the ratio 3:2 internally.(0 , 5)(1 , 21/5)(0 , 21/5)(1 , 5)
- 2. Multiple Choice3 minutes1 ptIn what ratio does the y-axis divide the line segment joining the point P (-4,5) and Q(3,-7)?3:54:32:15:3
- 3. Multiple Choice2 minutes1 ptFind the distance between (-12, 1) and (12, -1).24.0524.0624.0724.08
- 4. Multiple Choice1 minute1 pt
How is the distance formula correctly written:

$d\ =\ \sqrt{\left(y_{1\ }-\ y_2\right)^2\ -\left(x_{2\ }-\ x_1\right)^2}\$

$d\ =\ \sqrt{\left(x_{2\ }-\ x_1\right)^2\ +\ \left(y_{2_{\ }}-\ y_1\ \right)2}$

$d\ =\ \sqrt{\left(y_{1\ }-\ y\ _2\right)^2\ +\ \left(x_{2\ }-\ x_1\right)}^2$

d = $\sqrt{\left(x\right)^2-\ \left(y\right)^2}$

- 5. Multiple Choice2 minutes1 pt
A(3,1) B(-2,-1) written correctly is:

$\sqrt{\left(-2-3\right)^2\ +\ \left(-1-1\right)^2}$

$\sqrt{\left(1-3\right)^2\ +\ \left(-1-2\right)^2}$

$\sqrt{\left(-2-3\right)^2\ -\ \left(-1-1\right)^2}$

$\sqrt{\left(-2-3\right)^2\ -\ \left(-1-1\right)^2}$
