Write the equation of the perpendicular bisector of xy if endpoint x is at (-9,1) and endpoint y is at (3,5). a) y = -x b) y = 3x - 6 c) y = -3x - 6 d) y = 3x + 12

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

I'm confused on this could anyone me and show me what i need to do to solve it.
