Jeffery Pearson · Answer 1

4√2 units (Answer C).

Step-by-step explanation:

Going from the seat at (-4,6) to the one at (0,10), x increases by 4 units and y increases by 4 units. We need to use the distance formula to determine how far apart these seats are.

d = √ (change in x) ^2 + (change in y) ^2).

That works out to:

d = √ (4^2 + 4^2) = √ (32) = 4√2 units (Answer C).
