Answer:
• David
,• 4 miles
Explanation:
In the graph:
The given locations are:
• Owen's House, A(11,3)
,• David's House, B(15,13)
,• School, C(3,18)
We determine both Owen's and David's distance from the school using the distance formula.
Owen's distance from school (AC)
David's distance from school (BC)
We see from the calculations that David lives closer to the school, and by 4 miles.
The graph below is attached for further understanding:
