 # Find Distance, Slope and Equation of Line - Calculator

This calculator finds the distance between two given points A (xA , yA) and B (xB , yB), the slope and the equation of a line trough the two points.

## Formulas for Distance, Slope and Equation Given 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)

## Use of Distance, Slope and Equation of Line 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.
 A = (1 , 2) B = (3 , 4) Decimal Places = 3 Slope = d(A,B) = Equation: x intercept: y intercept:
