Two students are using the distance formula to determine the distance between (9, 4) and (–3, 8) on a coordinate grid. Their work is shown below.
Karlin’s Work
d = StartRoot (9 minus (negative 3)) squared + (4 minus 8) squared EndRoot. D = StartRoot (12) squared + (negative 4) squared EndRoot. D = StartRoot 144 + 16 EndRoot. D = StartRoot 160 EndRoot.
Abby’s Work
d = StartRoot (negative 3 minus 9) squared + (8 minus 4) squared EndRoot. D = StartRoot (negative 12) squared + (4) squared EndRoot. D = StartRoot 144 + 16 EndRoot. D = StartRoot 160 EndRoot.
Which best explains why the order in which the subtraction occurred did not cause a difference in the answers determined by the two girls?
ANSWER CHOICES :
-The differences are each squared.
-The differences are added together.
-The square root of the differences is taken.
- The differences are the same regardless of order.
