If the line has a slope of 4, then a line perpendicular to it would have a slope of -1/4.
If the line has a slope of -4, then a line perpendicular to it would have a slope of 1/4.
The relation of slopes between two perpendicular lines is m1*m2=-1
Cramer's rule is an explicit formula for the solution of a system of linear equations. That has many equations as unknowns and valid whenever the system has a unique solution.
