graph:
y=[-3x+5]
------------
To plot a few points find the zero value for y:
-3x+5 = 0
x = 5/3
That give you the point (5/3,0)
Plot a few points to the right and the left to see the slope:
If x=2, y = 1
If x=3, y = 4
If x=1, y = 2
If x=0, y = 5
Plot those points and draw a line where you can:

Start with the given equation

Break up the absolute value equation into two parts. Remember becomes or

or

For the first equation, multiply both sides by -1 to make y positive

Distribute

So we now have these two equations

or

Now graph the two equations

Graph of (red) and (green)

Remember, an absolute value graph is in a "V" shape, so that means the graph is the left branch and is the right branch.

So just erase the portions of the graph below the intersection like this
