What is the slope of a line perpendicular to 2y = -6x - 10? Select the correct option.
A) 3  B) -3  C) -1  D) 1/3  E) -1/3
For lines to be perpendicular ,   slope of line 1 * slope of line 2 = -1   (-6/3) * (x) = -1   x = (1/3)   where x is slope of line 2   Ans - 1/3
<result>D</result>
What is the slope of a line perpendicular to 2y = -6x - 10?
