Find an equation for the perpendicular bisector of the line segment whose endpoints are (5, 4) and (-7, -8).

Can someone answer it, and plot it, for 20 points and brainliest answer? p. s. they're the same ! : )

y=2x−1 5x−4y=1 is (1,1)(1,1) a solution of the system?

20 points for the answer. this is for real , don't put random ! a rectangle has a length of 4 centimeters and a width of 7 centimeters. what is the effect on the perimeter when the dimensions are multiplied by 5? the perimeter is increased by a factor of 5. the perimeter is increased by a factor of 20. the perimeter is increased by a factor of 25. the perimeter is increased by a factor of 100.
