Question

Points (0,0) and (3,3) lie on line k what is the slope of the line that is perpendicular to k

Answer 1

Slope equation: y2-y1 over x2-x1 
3-0 over 3-0 = 1 
to get the perpendicular slope of a line, you must use the negative reciprocal therefore, the slope of a line that is perpendicular to k is equal to -1
