Question 935218
Graph the inequality 
3x-7y<-21
----
7y > 3x+21
---
y > (3/7)x + 3
------
Sketch the line y = (3/7)x + 3 as a dashed line.
Use points (0,3), (-7,0)
Shade the half-plane ABOVE the dashed line because
you want y GREATER THAN (3/7x)+3.
----
{{{graph(400,400,-10,10,-10,10,y>(3/7)x+3)}}}

Cheers,
Stan H.
