Find an equation for the perpendicular bisector of the line segment whose endpoints are (-5,-3)(−5,−3) and (7,-7)(7,−7)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

i agree because i see the other persons thinking is clear
