Given the points:
( -9, 10 )
(11, 10)
x1= -9
x2 = 11
y1 = 10
y2 = 10
Find the length between the two points.
The length between the two points can be solve using the distance formula.
Formula for the length between two points:
d=√((x2- x1)²+( y2- y1)²)
Solution:
In order to determine the length 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=√((11 - (-9))²+( 10 -10)²)
d=√((11 + 9)²+( 0 ) ²)
d=√((20)²)
d=√400
d = 20
Final answer:
The length of the two points is 20 units.
