$()$ point$)$ For the lines defined by the following equations indicate with a $"V"$ if they are vertical, an $"H"$ if they are horizontal, and an $"$S$"($for slanted$)$ if they are neither vertical nor horizontal.

$3x+4y+5=0$

$4y+5=0$

$3x+5=0$

$x=1$

$y=1$

$y=x$

Hint: $(1)$ You can draw the graphs of these lines or $(2)$ put each equation in standard form $Ax+By=C.$ What is the form of an equation for a vertical line? What about a horizontal line?
