the directions are to solve these, then pick one point that is a solution, then one point that is not a solution that satisfies the equation as being true.
3x-y<-4
2x+4y<=-12...[the <= means greater than or eaual to]
now these say solve the systems of inequalities by graphing. name one point that is a solution and one point that is not.
y>1/2X-3
y<2x
y
x-y<=2
x+2y>=1
3x-2y<=-1..[that is not "equals" -1..it is less than or equal to]
x+4y>=-12

Draw the graph of 3x - y = -4 The line graph should br drawn in dots or dashes.
Decide where to shade - ie above the line or below it and shade.
Draw the graph of 2x + 4y = -12 The line here should be a solid line
Decide where to shade - above or below and shade.
Pick your points.
Repeat the process
The line of the graph is dotted (or in dashes) when there are no " = " signs in the inequality.
