If a_(1)<(28)^(1/3)-3

Prove that the points (a,b),(a_(1),b_(1)) and (a-a_(1),b-b_(1)) are collinear if ab_(1)=a_(1)b

If the points (a_(1),b_(1))m(a_(2),b_(2))" and " (a_(1)-a_(2),b_(2)-b_(2)) are collinear, then prove that a_(1)/a_(2)=b_(1)/b_(2)

If the points (a_(1),b_(1))m(a_(2),b_(2))" and " (a_(1)-a_(2),b_(2)-b_(2)) are collinear, then prove that a_(1)/a_(2)=b_(1)/b_(2)

If a_(1) lt ( 28)^((1)/( 3)) - 3 lt b_(1) , then (a_(1) b_(1)) ( a_(1) , b_(1)) is

If a_(1) lt ( 257)^(1//4) -4 lt b _(1) , then (a_(1) , b_(1) ) ( a_(1) , b_(1)) is

If (b_(2)-b_(1))(b_(3)-b_(1))+(a_(2)-a_(1))(a_(3)-a_(1))=0 then plove that the circumcenter of the triangle having vertices (a_(1),b_(1)),(a_(2),b_(2)) and (a_(3),b_(3)) is ((a_(2+a_(3)))/(2),(b_(2+)b_(3))/(2))

If the equation of the locus of a point equidistant from the points (a_(1),b_(1)) and (a_(2),b_(2)) is (a_(1)-a_(2))x+(b_(1)-b_(2))y+c=0 then the value of c is

If the equation of the locus of a point equidistant from the points (a_(1),b_(1)) and (a_(2),b_(2)) is (a_(1)-a_(2))x+(b_(1)-b_(2))y+c=0 then the value of c'is:
