The difference in the y-values of two points on a line is equal to the vertical distance between those points. This difference is also known as the "rise" or the "change in y."
To calculate the difference in the y-values of two points (y₁, x₁) and (y₂, x₂) on a line, you simply subtract the y-coordinate of one point from the y-coordinate of the other:
Difference in y-values = y₂ - y₁
This calculation gives you the vertical distance between the two points on the line.

The distance between any two points on a number line is the absolute value of the difference of the coordinates.
To find the slope we need to divide the difference in rise between these two points by the difference in run between them. The difference in rise equals: 3-2 = 1. The difference in run between these points equals: 2-4 = -2.Now we just divide 1/-2 and we get the slope of the line formed by these two points: -0.5

No. Three points do. Two points determine a line.
A perpendicular line is one that is at right angle to another - usually to a horizontal line. A perpendicular bisector is a line which is perpendicular to the line segment joining two identified points and which divides that segment in two.
