İf you have anything that not Clear,respond me
5r=20 10p=100 14t=42
100+42+20=162
5r+10p+14t=$162
Plot a point at the y-intercept of -2 or y = -2
--------------------------------------------------------------------
From there make a straight horizontal line
---------------------------------------------------------------
Then Shade the upper-half of that line one color This shaded part stands for
Y > -2
-----------------------------------------------------------------------
Shade the lower half a different color, this stands for y ≤ 6
-------------------------------------------------------------------------
That should be it!
