You can  put this solution on YOUR website! find the distance between the pair of points (-1,-4) and (-5,-7). 
ANS:- D=SQRT{[(-1)-(-5)]^2+[(-4)-(-7)]^2}=SQRT{9+9}=3SQRT(2) 
Find the midpoint of the line segment with the given end points: (2,1) and (6,8). 
ANS:-M=[(6-2)/2,(8-1)/2]=(2,3.5) 
Find the distance between thepair of points (-2,-6) and (7,-3). 
ANS:- D=SQRT{[(-2)-(7)]^2+[(-6)-(-3)]^2}=SQRT{81+9}=3SQRT(10) 
Write the standaed form of the quation of the circle with the given center  
(-2,-4) and radius 6. 
ANS:-[x-(-2)]^2+[y-(-4)]^=6^2 
or[x+2]^2+[y+4]^2=36 
can be simplified to 
x^2+4x+y^2+8y=16 ans
