What is the slope of a line perpendicular to the line - 3x + 6y = - 15?

slope of a line perpendicular to the line - 3x + 6y = - 15 is - 2

Step-by-step explanation:

-3x + 6y = 15

solve for y,

y = 1/2 x + 15/6

slope of a line perpendicular is the "negative reciprocal" of the slope of the original line, thus

y = - 2 x + b

The slope of a line perpendicular to the line - 3x + 6y = - 15 is 2
