Layana's house is located at (2 2/3, 7 1/3) on a map. The store where she works is located at (-1 1/3, 7 1/3). What is the distance from Layana's home to the store?

4 units

Step-by-step explanation:

Since the two different locations have the same y-component (7 1/3), we need not consider y when calculating the distance between L's house and L's store.

Instead, find the distance from - 1 1/3 to 2 2/3 along the x-axis.

That would be 2 2/3 - [-1 1/3], or 2 2/3 + 1 1/3, or 4 units of distance.

Answer: 4.

Step-by-step explanation: In this case it is easier to imagine it on the number line: the y coordinates are the same, so the distance is only in x direction. On the positive side it is 2 2/3 to zero and on the negative, 1 1/3 to zero. Total is 1 1/3 + 2 2/3 = 4. Or the proper writing: 2 2/3 - (-1 1/3) = 4
