Answer:
C
Explanation:
A (- 6, - 8 ) and C (9, - 8 )
since the y- coordinates of both points are equal, both - 8
then AC is a horizontal line
the distance AC can be calculated by calculating the absolute value of the x- coordinates, that is
AC = | 9 - (- 6) | = | 9 + 6 | = | 15 | = 15 units
or
AC = | - 6 - 9 | = | - 15 | = | 15 | = 15 units
given 1 unit =
mile , then
AC = 15 units = 15 ×
= 7.5 miles
