Morgana is finding the distance between points S and R. She says the distance is 1 unit. What did she do wrong? flocabulary A:She subtracted the y-coordinates instead of the x-coordinates.
B:She multiplied the absolute values of the x-coordinates instead of subtracting them.
C:She subtracted the absolute values of the x-coordinates instead of adding them.
D:She added the y-coordinates instead of the x-coordinates.
