You can put this solution on YOUR website! step by step, how you would go about graphing the following inequality.
X + 2y ≥ 6
--------------
Since it's a straight line, only 2 points are needed, any 2 points.
View it as an equation to find 2 points:
x + 2y = 6
Let x = 0: y = 3 --> (0,3)
Let y = 0: x = 6 --> (6,0)
Plot the 2 points and draw a straight line thru them.
The line has a negative slope, descends as you go left to right.
---------------------
The inequality is the area above and to the right of the line, and includes the line. For all points in that area, x + 2y is greater than or equal to 6.
For example, the point (5,5) --> 5+10 = 15. 15 is greater than 6.
