You can put this solution on YOUR website! 3x - 7y < -21
-7y < -3x - 21
y < (-3/-7)x - (21/-7)
y < (3/7)x + (21/7)
---
find two points on the graph:
---
x = 0
y = (3/7)0 + (21/7)
y = 3
(0,3)
---
x = 7
y = (3/7)7 + (21/7)
y = (21/7) + (21/7)
y = (42/7)
y = 6
(7,6)
---
on a piece of graph paper draw a dotted line through both points
---
the graph of the inequality is the area below the dotted line, because of the "y <" condition

You can put this solution on YOUR website! 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.
