Given:
P ( 8, 2 )
Q ( 3, 8 )
x1 = 8
x2 = 3
y1 = 2
y2 = 8
Determine the distance between two points.
d=√(( x2- x1)²+( y2 - y1)²)
Solution:
Substitute the given values of x1, x2, y1, and y2, to the distance formula.
d=√(( x2- x1)²+( y2 - y1)²)
d=√(( 3 - 8 )²+( 8 - 2)²)
d=√(( 5 )²+( 6)²)
d=√( 25+ 36)
d=√61
d = 7.8 units
Final answer:
d = 7.8 units
