Question

A(X,
4. Find all possible values of y for which the distance between the points
A(2, -3) and B(10, y) is 10 units.​

Answer 1

Answer:

3, -9

Step-by-step explanation:

AB = 10

Squaring both sides

AB² = 10²

(√[(10-2)²+(y-(-3))²])² = 100

8²+(y+3)² = 100

( y+3)² = 100-64

y+3 = ± √36

y+3 =± 6

if y +3 = 6

then y = 6-3 = 3

if y +3= -6

then y = -6-3 = -9

Answer 2

Answer:

3,-9
