Question

The lines shown below are perpendicular. If the green line has a slope of 23/1,what is the slope of the red line?-510-9-1051015XOA. 3/4OB.4/3O C.-4/3O D. -3/4MIN

Answer 1

Step 1

Two lines are perpendicular if the product of their slope = -1

Step 2

`m1* m1=\text{ -1}`

Step 2

`\begin{gathered} m1\text{ = }(3)/(4) \\ \\ (3)/(4)m2\text{ = -1} \\ \\ 3m_2\text{ = -4} \\ \\ m_2\text{ = }(-4)/(3) \end{gathered}`
