# Write a system of linear inequalities to represent each graph

Less than or equal to and we're done. Graphically, we can represent a linear inequality by a half-plane, which involves a boundary line.

And so you could actually, if you wanted to, you could say, "What pairs of C and M "satisfy both of these inequalities?

Determine if the boundary line should be dotted or solid that is, check whether the inequality is strict or inclusive, respectively. And so if you add them together, this is a total sugar that she's using and we're told that she needs to use up at least grams of sugar.

Well, we're told right over here she requires 35 grams of sugar per cupcake. Introduction A solution of a system of linear equalities is any ordered pair that is true for all of the equations in the system.

So this is how much sugar total she's going to use on the cupcakes. After completing this tutorial, you will be able to complete the following: Write a system of linear inequalities in two variables that corresponds to a given graph.

Now let's see, this next question. The boundary line is precisely the linear equation associated with the inequality, drawn as either a dotted or a solid line.

## Solving systems of linear inequalities worksheet answers

Well, we're told right over here she requires 35 grams of sugar per cupcake. In this example, we can use the origin 0, 0 as a test point. This is an inclusive inequality since it can be interpreted as or meaning we wish to include the equality. Less than or equal to and we're done. Well, that's going to be 30 grams of sugar per muffin. Finally, our graph should include the points x, y which satisfy the inequality We can determine these points by taking a point on one side of the line and testing its coordinates in our inequality. So no more than grams. A linear inequality on the plane can have one of the following forms: Notice that all of these linear inequalities have linear equations, which can be associated with them if we replace the inequality with an equality. Let's see, "Write an inequality that represents "the condition based on the number of grams of flour. If the inequality is of the form then the region below the line is shaded and the boundary line is solid. She needs to use at least grams of sugar to make both of these. And so you could actually, if you wanted to, you could say, "What pairs of C and M "satisfy both of these inequalities? So how much sugar she's gonna use for the cupcakes?
