Question 619753
How do I graph y is less than or equal to -4x+4?

First graph the line y = -4x + 4.  That's the boundary line of the
shaded region.  Draw it solid since it's less than or equal to.

{{{drawing(400,400,-6,6,-6,6,graph(400,400,-6,6,-6,6),line(-16,68,11,-40) )}}}

Since it's less than, shade the area under the graph:

{{{drawing(400,400,-6,6,-6,6,graph(400,400,-6,6,-6,6),line(-16,68,11,-40) 
graph(400,400,-6,6,-6,6,-4x+4,y<=-4x+3.5), graph(400,400,-6,6,-6,6)
)}}}
