Use the distance formula

d = sqrt((x2-x1)^2+(y2-y1)^2)

Remember that the two generic points are (x1, y1) and (x2, y2)

So (x1, y1) = (-2, 3), which means x1=-2 and y1=3

and (x2, y2) = (1, -1), which means x2=1 and y2=-1

So in short, x1=-2, y1=3, x2=1, and y2=-1.

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

d = sqrt((x2-x1)^2+(y2-y1)^2)

d = sqrt((1-(-2))^2+(-1-3)^2)

d = sqrt((1+2)^2+(-1-3)^2)

d = sqrt((3)^2+(-4)^2)

d = sqrt(9+16)

d = sqrt(25)

d = 5

So exact distance between the two points is 5 units.
