Suppose noodle soup is on sale for \$0.75 a can and you have a coupon for \$0.50 off your total purchase. Write a function rule for the cost of n cans of soup. (1 point) C(n) = 0.75n – 0.5 C(n) = 0.5n – 0.75 C(n) = (0.75 + n) – 0.5 C(n) = (0.5 + n) – 0.75

Oh my gosh I just learn that today and my notes are at school. I wish I could help. Sorry!

4. Bri_Durbin

ok what about a different one?

5. JazzyMLee9

Another question you meant

6. Bri_Durbin

Find the slope of the line. graph (1 point) 1/5 –1/3 –3 5

8. JazzyMLee9

Oh my gosh we haven't learn that yet. Again Sorry

9. Bri_Durbin

its ok

Suppose noodle soup is on sale for \$0.75 a can and you have a coupon for \$0.50 off your total purchase. Write a function rule for the cost of n cans of soup. (1 point) n = number of cans 0.75 per can. Subtract 0.50 from you're total purchase. Which works: 0.75n – 0.5 0.5n – 0.75 (0.75 + n) – 0.5 (0.5 + n) – 0.75

For the slope of the graph I need you to, either (1) show me a picture, or (2) give me two points on the line. Take a screenshot or save the picture and attach it.

@Bri_Durbin

14. Bri_Durbin

A for the first one right?

15. jazy

you got it (;

16. Bri_Durbin

and here is the link for the graph https://www.connexus.com/content/media/680582-9112012-123955-PM-1898319252.png

The link only works for you since you are a student there, but not for us. I have no access to it. /:

18. jazy

*to the picture in the link.

19. Bri_Durbin

i think that it is -3 for the graph it that right???

20. jazy

I can't see the graph. But if you know that slope is rise/run, you should be able to figure it out. (:

21. Bri_Durbin

22. jazy

Right! (:

23. Bri_Durbin

there is the graph and was it A for the first question???

24. jazy

Yes.

25. Bri_Durbin

so is it -3 for the graph?

26. jazy

Yes, -3 is the slope of the graph.

27. Bri_Durbin

Write an equation in point-slope form for the line through the given point with the given slope. (–7, 9); m = 4/5 (1 point) y + 7 = 4/5(x – 9) y – 7 = 4/5(x + 9) y – 9 = 4/5(x + 7) y + 9 = 4/5(x – 7) you are the best can i have help with a few more???

28. Bri_Durbin

I think that it is B???

29. jazy

Point-Slope form is y - y1 = m(x - x1) m is slope x1 and y1 stand for the x and y vaues of the given point (x, y) (–7, 9) m = 4/5 Plug in the values. y - 9 = 4/5(x -(-7)) Two negative signs(--) equal a positive(+) so... y - 9 = 4/5(x + 7)
