Solved by pluggable solver: Distance Formula


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


Since the first point is (1, -3), we can say (x1, y1) = (1, -3)
So ,


Since the second point is (-2, 6), we can also say (x2, y2) = (-2, 6)
So ,


Put this all together to get: , , , and

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


Now use the distance formula to find the distance between the two points (1, -3) and (-2, 6)






Plug in , , , and

























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

Answer:


The distance between the two points (1, -3) and (-2, 6) is exactly units


The approximate distance between the two points is about 9.48683298050514 units



So again,


Exact Distance: units


Approximate Distance: units





The approximate distance is roughly 9.48683298050514 units

So you round that to the nearest hundredth to get 9.49 which is your final answer (if you decide to report the approximate answer over the exact answer)
