Question

(-3,1) and (-1,1) would the answer be |-3|+|-1|= 4 is it correct and why if not why in 2 sentences explaining if I would suppost to add or subtract

Answer 1

Not correct — you should subtract the x-coordinates and take the absolute value rather than add their absolute values. The distance is |(−1) − (−3)| = |2| = 2 (or using the distance formula sqrt((−1+3)^2 + (1−1)^2) = 2).
