Solution
## $$y+2x=5$$ can be written as $$y=-2x+5$$ which is of form $$y=mx+c$$ Comparing we get, $$m=-2$$So slope is$$(-2)$$Physics

Two angles are said to be complementary if the sum of their measures is $90^\circ.$
The given angle is $60^\circ$
Let the measure of its complement be $x^\circ.$

Let $\RR$ be a relation on a set $S$.
Let $\RR$ be transitive.
Then its inverse $\RR^{-1}$ is also transitive.
