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) = (-6, 2), which means x1=-6 and y1= 2
and (x2, y2) = (4, -1), which means x2=4 and y2= -1
So in short, x1=-6, y1= 2, x2=4, and y2= -1.
-------------------
d = sqrt((x2-x1)^2+(y2-y1)^2)
d = sqrt((4-(-6))^2+( -1- 2)^2)
d = sqrt((4+6)^2+( -1- 2)^2)
d = sqrt((10)^2+(-3)^2)
d = sqrt(100+9)
d = sqrt(109)
So exact distance between the two points is sqrt(109) units.
