Answer:
m_b = 1/2
Step-by-step explanation:
The slope of a perpendicular equation is always the negative inverse of the original slope. [tex]m_{p} =-(\frac{1}{m} )[/tex]
This basically mean:
1. flip the sign -2 --> 2 = [tex]\frac{2}{1}[/tex]
2. then flip the numerator and denominator [tex]\frac{2}{1}[/tex] --> [tex]\frac{1}{2}[/tex]
