1.

The given point are A(1, 5) and B(4, 6).

Let the line CD be the perpendicular bisector of line segment AB.

Suppose CD intersect AB in E.

∴ Coordinates of E

Let the slope of CD be m.

Since AB ⊥ CD,

∴ Slope of CD × Slope of AB = – 1

∴ Equation of CD is

∴ Equation of perpendicular bisector line segment AB is 6x + 2y – 26 = 0.

We know that, on the y-axis, x = 0.

Putting x = 0 in 6x + 2y – 26 = 0, we get

0 + 2y – 26 = 0

∴ 2y = 26

y = 13

Thus, the perpendicular bisector of line segment AB cuts y-axis at (0, 13).

2.

Given, P(2, 1) lies on the line segment joining A(4, 2) and B(8, 4).

Using distance formula,

3.

The points A( – 3, – 1), B( – 4, – 1), C(  3, 3) and D( 4, 3) are not the vertices of the rhombus.
