You can put this solution on YOUR website! I can't get this program to graph inequalities, but I'll try and talk you through it.
Solve the inequality for y:
Let x=0 and y=?
Plot (0,5)
Let x=3 and y=?
Plot (3,10)
Connenct the points.
Because y is greater than or = to the line shade above the line.
The line without shading looks like:
Happy Calculating!!!
