You'll have three copies of the red "-x" rectangles to represent -3x
Next, you'll need five copies of the blue squares with the label "1". This represents 5 since 1*5 = 5.
Lastly, you'll need one copy of the purple rectangle that has "y" on it.
All of this forms the expression -3x+5+y
All of these figures will be above the dashed line to be in the positive region.
