Question

James has mapped his seat and his teacher's seat on the coordinate plane at (0,10) and (–4,6). Find the distance between their seats. A. 4√ 17 units B. 16 units C. 4√ 2 units D. 4 units

Answer 2

4√2 units (Answer C).

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).
