Explanation:

The first graph , is for ;

$r < -2\\\\\begin{bmatrix}\mathrm{Solution:}\:&\:r<-2\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-2\right)\end{bmatrix}\\$

The second graph is for ;

$x< 5\\\\\begin{bmatrix}\mathrm{Solution:}\:&\:x<5\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:5\right)\end{bmatrix}\\$

The third graph is for ;

$-x>2\quad \\\\\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}\\\\\left(-x\right)\left(-1\right)<2\left(-1\right)\\\\x<-2\\\\\begin{bmatrix}\mathrm{Solution:}\:&\:x<-2\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-2\right)\end{bmatrix}$
