We prefer that the answers are defined in RR to the second power (I don't know what RR to the second power means). Answer graphically each answer in the same cartesian coordinate system.
f(x)=2x
h(x)=2x+2
g(x)2x-1
i(x)=2x-4

In a line $\displaystyle y=mx+b$, $\displaystyle m=\tan \theta$,$\displaystyle \theta$ is the angle between the line and the positive direction of the x-axis.
Here is a formula for you.
Given that $\displaystyle \theta$ is the angle formed from the line $\displaystyle y=mx+b$ to line $\displaystyle y=m'x+b'$, then
$\displaystyle \tan\theta=\frac {m'-m}{1+mm'}$
