Given the points:
( 2, 4 )
( 1, 1 )
x1 = 2
x2 = 1
y1 = 4
y2 = 1
Determine the distance between two points.
Formula for the distance between two points:
d=√((x2- x1)²+( y2- y1)²)
Solution:
In order to determine the distance between two points, we simply need to substitute the given values of x1, x2, y1 and y2 to the formula.
d=√((x2- x1)²+( y2- y1)²)
d=√((2 - 1)²+( 1 - 4)²)
d=√((1)²+(-3)²)
d=√(1 + 9)
d=√10
d = 3.16 units
Final answer:
The distance between two points is 3.16 units.
