The transformation which is represented is a 180 degree rotation about the origin
Perpendicular lines are lines that cross at a 90 degree angle
Lines AB and BC
In isosceles right triangle, legs are equal. Let each leg is of x units . And the given hypotenuse is 5 square 6. We use pythagorean identity here, which is

Where a=b=x and c= 5 square root 6




And that's the length of both the legs . ANd that's the required answer .
#1
y= 5x-7
y= -2/3x+3
#2
y=4/5x (+0)
y= -5/4x(+0)
