Work Step by Step

Using $y=mx+b$, where $m$ is the slope, the slope of $ f(x)=-2x+6 $ is \begin{array}{l} m_1=-2 \end{array} and the slope of $g(x)=2x-1$ is \begin{array}{l} m_2=2 .\end{array} Since $m_1\ne m_2$ and $m_1\cdot m_2\ne-1,$ then the given lines are $\text{ neither parallel nor perpendicular .}$
