21: How Do I Find the Break Even Point?

3. Warm - Up List characteristics for the 4 types of slope: Negative
Positive
Undefined
Zone

4. Hypothesize
What do you think the contextual meaning is of a line that cross through the x-axis?

5. Learning Intention/Success Criteria
LI: We are learning to find the break even point on a graph or equation
SC: I know how to -identify the m, b, and the x-intercept -explain parts of the equation in context of the problem

6. EQ: What is the Break Even Point?

7. The point where the profit and losses equal each other
Break Even Point
Normally where the line of the function crosses the x-axis

8. Is the slope of this function, P(x), positive or negative
Is the slope of this function, P(x), positive or negative? Explain in context.
Example 1: A lychee vendor must pay $25 for a booth where she sells lychee for $2 a pound
The slope of this function is positive.
For every pound of lychee sold, she gets $2.

9. What is the y-intercept of P? Explain in context.
The y-intercept is -25
The lychee vendor must pay $25 to open her booth.

10. Find the symbolic form for the linear function. Then, graph it.
P(x) = 2x - 25 30 20 10 4 8 12 16 20
-10
-20
-30

11. Based on your graph, where is the break even point?
The break even point is at The vendor would need to sell 12.5 pounds to break even and start making a profit.

12. Stations
To start, you will be working on one part of the Station as a group. Once every one finishes, you will break up into smaller groups (one from each station) and share answers.
If you have any questions, you can ask the sub about the answers
