Solved by pluggable solver: Distance Formula


The first point is (x1,y1). The second point is (x2,y2)


Since the first point is (-3, 4), we can say (x1, y1) = (-3, 4)
So ,


Since the second point is (1, -1), we can also say (x2, y2) = (1, -1)
So ,


Put this all together to get: , , , and

--------------------------------------------------------------------------------------------


Now use the distance formula to find the distance between the two points (-3, 4) and (1, -1)






Plug in , , , and
















==========================================================

Answer:


The distance between the two points (-3, 4) and (1, -1) is exactly units


The approximate distance between the two points is about 6.40312423743285 units



So again,


Exact Distance: units


Approximate Distance: units
