Graphing Linear Inequalities
Question | Answer |
---|---|
2x + y < 3 | http://yfrog.com/c8morethan3p Change to 2x + y = 3 and put in correct numbers that make it equal more than 3. Line on the graph should be DASHED. |
x + y >/= 5 | http://yfrog.com/mulessthan5p Change the solution to x+y=5 and plug in all correct numbers. Line on the graph should be SOLID. |
{x + y > 6 {x - y < 3 | http://yfrog.com/1rdouble63p Solve each problem separately. Then graph them both and the area that intersects is the solution area. Both lines are DASHED in this problem. |
3x + y | http://yfrog.com/mumorethan12p Change the equation to 3x + y = 12 and plug in all numbers that are equal to 12. Since this is equal to the line will be SOLID. |
x - 2y > -10 | http://yfrog.com/nfmorethanneg10p |
{2x + 2y >/= 0 {x - y < 2 | http://yfrog.com/nddouble02p |
