If the lines are perpendicular, then the slope of line n is the negative reciprocal of m. Line m passes through the origin so the x-intercept is 0. We don't have to know the x-intercept for n since anything times zero will also be zero.
Quantity A
m*n = -1
Quantity B
m*n =0
B>A
B is the correct answer.
Quantity A
m*n = -1
Quantity B
m*n =0
B>A
B is the correct answer.
