Question

The distance between the two points (2, -3) (10, y) is ten units find ‘y’.

please answer my question​

Answer 1

y=3

here is your answer

Answer 2

Answer:

d=√((x2-x1)²+(y2-y1)²)

10=√((10-2)²+(y+3)²)

squaring both sides

100 =8²+(y+3)²

100-64 =(y+3)²

36=(y+3)²

√(36)=(y+3)

y+3=+6&-6

y=3&-9
