Give a brute-force algorithm that finds the second largest element in a list a1, a2, an (n ≥ 2) of distinct integers by finding the largest element, placing it at the beginning of the sequence, then finding the largest element of the remaining sequence slader

Aline is perpendicular to another line m2= (-1/m1), where m1 is the slope of the original line and m2 is the slope of the perpendicular line. which of the following equations represents the line that passes through the point (-2,1) and is perpendicular to the line below?
