When two lines are perpendicular, the product of their slopes is -1.  To answer this question, find the slope of the linear equation given; To do this, solve it for y;   3y = -x + 5; divide both sides by 3:   y = -1/3 x  +  5/3; and the slope is the coefficient of the variable x.  In this case, the slope of the given line is -1/3.  The slope of the line perpendicular to the given line is found by computing the negative reciprocal of -1/3.  Look at your list of options and decide which one is the negative reciprocal of -1/3 and you should conclude that C is the correct answer.
