I need help with this question please!

Question

Your house is at (5,2) and the library is at (-3,2). What is the distance between the two locations? Do not include units. 

Answer 1

8

subtract: 5 -(-3) = 5+3. Just the difference in the x coordinates.

You can use the distance formula, but it's unnecessary when the y coordinates are the same. Just subtract one x coordinate from the other, and take the absolute value if it's negative

d^2 = (5+3)^2 + (2-2)^2 = 64

d = +sqr64 = 8
