# Writing and graphing inequalities pdf

Aunt Sally wants to sell 15 cookies and 10 glasses of lemonade. This point is below the line. Do we need to flip the inequality sign?

Determine if the solution set includes the area above or below the line, then pick any point and check your work. The sum of 15 cookies for an unknown price, x, plus 10 glasses of lemonade for an unknown price, y, has to be greater than or equal to 50 dollars.

Will Aunt Sally collect 50 dollars or more if she sells 15 cookies for 1 dollar each and 10 glasses of lemonade for 3 dollars each? From there, they will have the y-intercept and should be able to reason about the rate of change of the line. For y is greater than negative one-half x plus five, we use a dashed line as, the values on the line are not part of the solution set.

Opening 5 minutes The purpose of today's lesson is to allow students to practice what they have learned about writing and graphing inequalities thus far in the context of a new situation.

### Graphing one step inequalities

For y is greater than, we must use a dashed line, and only the values above the line are part of the solution set and lastly, for y is less than, the line is dashed and only the values below the line satisfy the inequality.

For y is less than negative x plus 4, we have to use a dashed line; but this time, the values below the dashed line are in the solution set. How about the ordered pair 1, 3? Once you have done that, using the y-intercept as your first point, use the slope to draw in additional points. For my birthday, she baked 15 cookies, trimming them with edible gold leaf, and she squeezed a bowl of lemons to make 10 glasses of lemonade, but then my mom reminded her that my birthday is not till next month. Aunt Sally wants to sell 15 cookies and 10 glasses of lemonade.

In my experience, most students prefer to write the inequality Clarita's way, by thinking through the math they need to do to take care of pampering time for both cats and dogs. Do the math. For my birthday, she baked 15 cookies, trimming them with edible gold leaf, and she squeezed a bowl of lemons to make 10 glasses of lemonade, but then my mom reminded her that my birthday is not till next month.
