If: y = 5x +10 and y = x^2 +4Then: x^2 +4 = 5x +10Transposing terms: x^2 -5x -6 = 0Factorizing the above: (x-6)(X+1) = 0 meaning x = 6 or x =-1Therefore by substitution endpoints of the line are at: (6, 40)and (-1, 5)Midpoint of line: (2.5, 22.5)Slope of line: 5Perpendicular slope: -1/5Perpendicular bisector equation: y-22.5 = -1/5(x-2.25) => 5y= -x+114.75Perpendicular bisector equation in its general form: x+5y-114.75= 0
