Question

If the distance between (8,0) and A is 7 , then coordinates of the point A cannot be: (2,0) (8,7) (8,-7) (0,-8)

Answer 1

Step-by-step explanation:

Distance between two points (x1,y1) and (x2,y2) can be calculated using the formula (x2−x1)2+(y2−y1)2

We can see that distance between (8,0) and (0,−8)=(0−8)2+(−8−0)2=64+64=82.

Hence, A cannot be (0,−8)
