The point where the perpendicular bisector of the line segment joining...
Method to Solve :

Perpendicular bisector = Cuts at mid point, and is perpendicular

First find the mid point
x coordinate = 1+4 / 2 = 2.5
y coordinate = 5+6 / 2 = 5.5
Mid point = (2.5, 5.5)

Then find the slope of the bisector :
Slope of the given line = (5-6) / (1-4) = 1/3
Slope of given line multiplied by slope of bisector = -1
Slope of bisector = -1 / (1/3)
= -3

Use the point slope form to find the bisector's formula :
-3 = (5.5 - y) / (2.5 - x)
-7.5 + 3x = 5.5 - y
3x + y - 13 = 0

Transform the formula into slope-intercept form

3x + y - 13 = 0
y = -3x + 13

Because slope-intercept form is y = mx + c, where m is the slope and c is the y-intercept

Therefore the perpendicular bisector cuts the y-axis at (0,13)

The point where the perpendicular bisector of the line segment joining...
To find the point where the perpendicular bisector of the line segment joining points A(2, 5) and B(4, 7) cuts, we can follow these steps:

1. Find the midpoint of the line segment AB:
- The midpoint formula is given by:
((x1 + x2) / 2, (y1 + y2) / 2)
- Substituting the coordinates of A and B:
Midpoint = ((2 + 4) / 2, (5 + 7) / 2)
= (6 / 2, 12 / 2)
= (3, 6)

2. Find the slope of the line segment AB:
- The slope formula is given by:
(y2 - y1) / (x2 - x1)
- Substituting the coordinates of A and B:
Slope = (7 - 5) / (4 - 2)
= 2 / 2
= 1

3. Find the negative reciprocal of the slope:
- The negative reciprocal of a slope is obtained by flipping the fraction and changing the sign.
- In this case, the negative reciprocal of 1 is -1.

4. Find the equation of the perpendicular bisector:
- The equation of a line in point-slope form is given by:
y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.
- Using the midpoint (3, 6) as a point on the line and the negative reciprocal slope (-1):
y - 6 = -1(x - 3)
y - 6 = -x + 3
y = -x + 3 + 6
y = -x + 9

5. Find the intersection point of the perpendicular bisector with the x and y axes:
- To find the intersection point with the x-axis, we set y = 0 in the equation of the line and solve for x:
0 = -x + 9
x = 9
- Therefore, the intersection point with the x-axis is (9, 0).
- To find the intersection point with the y-axis, we set x = 0 in the equation of the line and solve for y:
y = -0 + 9
y = 9
- Therefore, the intersection point with the y-axis is (0, 9).

6. Conclusion:
- The point where the perpendicular bisector of the line segment AB cuts is (9, 0), which corresponds to option B.
