Question 38197: Graph the following inequality and shade it - - include your coordinates in the spaces below. 4x + y > or = 4 ( , ) ( , ) I found one similar except it didn't have "or =" to in the equation just the greater than sign. Don't understand it. Thank you,

You can put this solution on YOUR website! The "or =" just means to make the graph with a SOLID line, which means that the line itself is included.
In my opinion the easiest way to graph this is to use the intercepts method and graph the line with an "=" sign only. We can handle the ">" sign later:
Let x = 0, then y=4.
Let y = 0, then 4x = 4, so x = 1. Graph these two points, and remember that if you have a POSITIVE Y-coefficient, the ">" or ">+" means to shade ABOVE the line. If you have a "<" or "<=" then it means to shade BELOW the line.
In this case you will have to graph with a SOLID line, and shade ABOVE the line. I don't know how to do this in algebra.com graphing so I'll graph the line, and YOU make it a SOLID LINE and SHADE ABOVE the line:
