There is something missing from this question. It cannot be answered as it appears.
A line segment is a straight line that has endpoints.
We're having a bit of trouble making out the line shown. "ab" and "ac" would not be the labels of a point ... they would be the labels of two line segments both emanating from the same point called "a". So your point has to be either 'b' or 'd' or both. We'll be able to put a finer point on it if you'll let us have a look at the picture of the line that goes along with the question.
Point B
Using a compass and ruler: # Label the ends of the line you wish to bisect as A and B. # Construct two circles centred at A and B, large enough that they almost reach the other point and have the same size. Label the points they intersect at as C and D. # Draw a straight line between C and D. The point it intersects the original line is the halfway point; any bisector must pass through that point.

On a horizontal line, the value of ( b ) would be constant, representing the y-coordinate of all points on that line. Since the line is horizontal, the value of ( b ) does not change regardless of the x-coordinate. Thus, for any point on a horizontal line, ( y ) equals ( b ).
In a number line, point A will appear to the left of point B if A is less than B. Conversely, if A is greater than B, it will appear to the right of B. If A and B are equal, they will occupy the same point on the number line.

The length of the line segment BB' is equal to the distance between point B and point B'.

The equation of a line in point-slope form is given by ( y - y_1 = m(x - x_1) ), where ( m ) is the slope and ( (x_1, y_1) ) is a point on the line. For the point ( (a, b) ) and slope ( b ), the equation becomes ( y - b = b(x - a) ). Simplifying this, we get ( y = bx - ab + b ) or ( y = bx - ab + b ).

The equation of a vertical line passing through the point (a, b) is x a.
If the point is x=a, y=b ie the point (a,b) , then your line is y-b=m(x-a) where m is the gradient (anything you like).
The fastest way from point A to point B is usually a straight line, as long as there are no obstacles in the way.
Point B
To reflect a figure across the line ( y = x ), you swap the coordinates of each point in the figure. For a point ((a, b)), its reflection would be ((b, a)). This process is applied to every point in the figure, resulting in the entire figure being mirrored across the line ( y = x ).
