# How do you solve and graph 5z<-90?

$z < - 90$; Graph $y = - 90$ and $y = 5 z$ on the same graph and shade below -90 and to the left of $5 z$.
$z < - 18$
You can graph this by first graphing -90 and then the line $y = 5 z$. Then shade all the spaces below -90 and the left of $y = 5 z$. It would look like this:
