Question

Lines a and b are perpendicular. The slope of line a is -2. What is the slope of line b?

Answer 1

Answer:

$\sf\boxed{ \sf \dfrac{1}{2} \ is \ the\ slope }$

If lines are parallel or tangent, the slope remains same.

$\sf \large\boxed{\sf m_1 \rightarrow m_2}$

If lines are perpendicular or normal, the slope becomes negatively inverse

$\sf \large\boxed{\sf m_1 \rightarrow -(\frac{1}{m_2} )}$

With this Here the line a is perpendicular to line b,

therefore using formula: $\sf \large {-(\dfrac{1}{-2} )} \rightarrow \dfrac{1}{2}$
