The distance between the house at (-9, 9) and the subway stop at (-5, 2) is determined by calculating the displacements (4 units horizontally and 7 units vertically ) and applying the Pythagorean theorem to find the hypotenuse. The distance is approximately 8.06, which rounds to 8 to the nearest unit. ;
A ( − 5 ; 2 ) ; B ( − 9 ; 9 ) ∣ A B ∣ = ( − 9 − ( − 5 ) ) 2 + ( 9 − 2 ) 2 = ( − 4 ) 2 + 7 2 = 16 + 49 = 65 ≈ 8 ( u ni t s )
The distance between the subway stop at (-5, 2) and your house at (-9, 9) is calculated using the distance formula, resulting in approximately 8 units when rounded to the nearest unit.
