1)(-8,0)(3,0)
Use the distance formula to find the distance between the two points.
d=sqrt%28%28x2-x1%29%5E2+%2B%28y2-y1%29%5E2%29
we are given (x1,y1)=(-8,0)and (x2,y2)=(3,0)
replace them in the above equation
d=+sqrt%28%283%2B8%29%5E2%2B%280-0%29%5E2%29
+d=+sqrt%28121%29
d=11
The distance between the pair of points is 11 units

2)(4,-6)(-1,6)
here (x1,y1)= (4,-6) and (x2,y2)=(-1,6)
d=13
3)(-6,-4) (-2,4)
here (x1,y1)= (-6,-4)and (x2,y2)=(-2,4)
d=4
