Question 86125: I have tried this for 2 days and still have not got the answer from the key. Could someone show me how to do this.
Graph each of the following inequalities.
4x+y greater than or equal to 4

You can put this solution on YOUR website!
Graph:
4x%2By+%3E=+4 Rewrite this as: y+%3E=+-4x%2B4 (Slope-intercept form)
To draw the graph, first treat this as an equation rather than an inequality:
y+=+-4x%2B4
graph%28300%2C200%2C-5%2C5%2C-5%2C5%2C-4x%2B4%29
Now, because the inequality is y+%3E=+-4x%2B4 the line on the graph is a solid line (rather than dotted).
Now you need to decide which side to shade and you do this by trying a point on the left side, let's say point (0, 0) and see if this point satisfies the inequality.
0+%3E=+-4%280%29%2B4
0+%3E=+4 Not, it does not!
So you shade the other side (right) of the line which then represents the area of all the solutions to this inequality.
