how many units are apart from 2,3 and 2,-2

Answer 1

d = sqr (sum of squares of the difference in x & y coordinates)

d = sqr(25 + 0) = sqr25 = 5

the two points have the same x value

the only difference is the y value. subtract one y value from the other to get the distance between the two points

3 minus -2 = 3+2 = 5

to subtract a negative number, change it to positive and add

3-(-2) = 3+2 = 5
