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

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.

A for the first one right?

- anonymous

you got it (;

and here is the link for the graph

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

*to the picture in the link.

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

- anonymous

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

Right! (:

- anonymous

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

- anonymous

Yes.

- anonymous

so is it -3 for the graph?

- anonymous

Yes, -3 is the slope of the graph.

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???

- anonymous

I think that it is B???

- anonymous

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)
