This calculator finds the distance between two given points A (xA , yA) and B (xB , yB), the slope and the equation of the line trough the two points.
This calculator uses the following formulas for the distance between two points
d(A,B) = sqrt [ (xA - xB) 2 + (yA - yB) 2 ]
The formula for the slope m
m = (yB - yA) / (xB - xA)
and the equation of a line in point slope form
y - yB = m (x - xB)
How to use the calculator
1 - Enter the x and y coordinates of two points A and B and press "enter". The distance between points A and B, the slope and the equation of the line through the two points will be calculated and displayed.
When the two points are on a vertical line (x coordinate of A equals the x coordinate of B), the slope is undefined and the equation of the line is of the form x = constant.
