10. Explain why it does not matter which point you choose when writing the
equation of the line in point-slope form, given two points.
11. Members of the student council are conducting a fundraiser by selling school
calendars. After selling 80 calendars, they had a loss of $360. After selling
200 calendars, they had a profit of $600. Write an equation that describes the
relation between y, the profit or loss, and x, the number of calendars sold. How
much profit did they make from selling each calendar? How much would they
have lost if they had sold no calendars?

Answer 1

Answer:

See my explanations below please :)

Step-by-step explanation:

4. y-1 = 3(x-2)

5. y+5= -2(x+3)

6. y+11 = (3/4)(x-4)

7. y = (-1/6)(x-4)

8. y+2 = (5/8)(x+3)

9. y-1 = (3/8)(x+5)

10. Because after simplifying them, the final equations are the same

11. so we have (80,-360) and (200, 600)

   m = (600-(-360)) / (200-80) = 960 / 120 =8

   => y+360 = 8(x-80)

  Profit selling each = the slope m = $8

  Working backwards, when they sold 80 calendars they still have a loss of $360, so the original loss (when x=0) = 80*8 + 360 = 640 + 360 = $1,000

Done :) Can I have a Brainliest plzzzzz ty!
