Question 7311
1)(-8,0)(3,0)
Use the distance formula to find the distance between the two points.

{{{d=sqrt((x2-x1)^2 +(y2-y1)^2)}}}
we are given (x1,y1)=(-8,0)and (x2,y2)=(3,0)
replace them in the above equation
{{{d= sqrt((3+8)^2+(0-0)^2)}}}
{{{ d= sqrt(121)}}}
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
