Graph the inequality
4x + y is greater than or equal to 4
4x%2By%3E=4
4x-4x%2By%3E=-4x%2B4
y%3E=-4x%2B4
Plot points the way you would an equality.
Let x=0 and solve for y:
y=-4%280%29%2B4
y=0%2B4
y=4 Plot (0,4)
Let x=1 and solve for y:
y=-4%281%29%2B4
y=-4%2B4
y=0 Plot (1,0)
Because the inequality contains =, connect the two points with a solid line like this:
graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C-4x%2B4%29
I don't have the capability of shading this graph for you, but you would shade above the line because y is greater than the rest of the graph.
Happy Calculating!!!
