Question

Which points are a distance of 5 units from (2, 3) if d = square root (x2 - x1)2 + (y2 - y1)?

Answer 1

Explanation:

hello :

note :

note : distance between A(X1,Y1) an B (X2,Y2) is :

AB= √((X2 - X1)² + (Y2 - Y1)²) (given point B(2 , 3)

in this exercice : X1 = 2 X2 = ? Y1 = 3 Y2 = ? d=AB=5

d² = (X2 - 2)² + (Y2 - 3)² =25

the points are a distance of 5 units from B (2, 3) if d = 5 :

the points are located on a circle with center B and radius 5
