You can put this solution on YOUR website! I have a graph where x-axis and the y-axis meet. I need to graph the following inequalities:
4x + y > 4
- (there is a line under the >)
-------------
4x+y>=4
Solve for y as follows:
y>=-4x+4
Graph the EQUALITY using points:
If x=0, y=4 giving you point (0,4)
If x=1, y=0 giving you pont (1,0)
Plot these points and draw a line thru them.
That is the graph of the EQUALITY.
Since you also want the points that satisfy the
INEQUALITY and the inequality is > you shade
the half-plane ABOVE the line you just drew;
That half-plane is the graph of the INEQUALITY.
Line and the half-plane together are the graph
solution of you problem.
