[4.07]What is the slope of the line passing through the point (3, −4) and perpendicular to the line y = 3x + 5? Write your answer as a fraction

Question

anonymous · Answer

Do you need the slope only? That will be -1/3. If you need the equation, substitute the point (3,-4) into y=-1/3x + c to get c

anonymous · Answer

yes please

hartnn · Answer

u get -1/3 because the product of slopes of perpendicular lines is -1
so x*3=-1
so x=-1/3
