Question

What is the slope of any line perpendicular to the line passing through `(14,12)` and `(12,5)`?

Answer 1

Slope = `-2/7`

Explanation:

Slope of the perpendicular line is `(y_2-y_1)/(x_2-x_1) = (5-12)/(12-14)=7/2` We know the condition of perpendicularity of two lines is the product of their slopes will be equal to be `-1`.i.e `m_1*m_2=-1 ; m_1=7/2 :. m_2= -2/7`[answer]
