GRAPH THE EQUATION 7x+3y=21
----
If x = 0, y = 7
If y = 0, x = 3
---
Plot (0,7) and (3,0) and draw a line thru them:

Express in terms of +y+
+7x+%2B+3y+=+21+
Subtract +7x+ from both sides
+3y+=+-7x+%2B+21+
Divide both sides by +3+
+y+=+-%287%2F3%29%2Ax+%2B+7+
Heres the plot:
+graph%28+400%2C+400%2C+-10%2C+10%2C+-10%2C+10%2C+-%287%2F3%29%2Ax+%2B+7+%29+
