Question

Line L passes through the points (4, -5) and (3, 7). Find the slope of any line perpendicular to line L.

• A. 12
• B. -1/2
• C. - (1/12)
• D. 1/12

Answer 1

The correct option is D

1/12

Slope of the line L = (7-(-5))/ (3- 4) = -12

Slope of the line perpendicular to the given line = - (1/$m_1$)

So, Slope of line perpendicular to L = $\frac{1}{12}$
