Question

Find out all possible values of y for which distance between points A(2,-3) and B(10,y) is 10 units

Answer 1

Answer:

By distance formula:

d=√(X-x)^2+(Y-y)^2

Step-by-step explanation:

10= √(10-2)^2+(y-(-3))^2

By squaring on both sides:

100=8^2+(y+3)^2

100=64+(y+3)^2

36=(y+3)^2

By taking square root on both sides:

6=y+3

y=6-3

y=3
