The average cost represents the slope of the line of the graph.
Increasing the slope of the graph increases the steepness of the line.
Therefore, increasing the average cost of gas from $1.50 to $2.20 will increases the steepness of the line. (i.e. the line becomes closer to the vertical line).

Which equation represents a linear equation?
AlekseyPX

Answer:

y - 2 =  - 5(x - 2)

Step-by-step explanation:

y - 2 =  - 5(x - 2) \\ y - 2 =  - 5x + 10 \\ y =  - 5x + 10 + 2 \\ y =  - 5x + 12 \\ y  = 12 - 5x \\

Describe a real-world situation that can be modeled by the function y=2x-3.
lara [203]

Yes you have a good example.

x = number of cookies

2*x = total amount spent on cookies at $2 each

2x-3 = amount you pay after the $3 discount is applied one time for the entire order

-------------

a more numeric example may be this

Lets say you bought 12 cookies, so x = 12

This means it costs 2*x = 2*12 = 24 dollars total if the discount doesnt apply

However, the 3 dollar discount is there, so the grand total is 24-3 = 21 dollars.

For this case we have the following table:
 X    F(x) 
 -1   -11 
 0    -1 
 1     9
 From here, we look for the function f (x).
 We then have that as the equation is linear:
y-yo = m (x-xo)

 Where,
 m = (y2-y1) / (x2-x1)


 m = (9 - (- 1)) / (1-0)

 m = (9+1)/(1)

m = 10
 We choose an ordered pair:
 (xo, yo) = (0, -1)

 Substituting values:
 y + 1 = 10 (x-0)

 Rewriting:
 y = 10x - 1

 Thus, the function f (x) is:
 f (x) = 10x - 1

 On the other hand, the function g (x) is:
 g (x) = 5x +1

 Answer:
 
The slope of f (x) is greater than the slope of g (x) (10> 5)
 
The intersection with the y axis of g (x) is greater than the intersection with the y axis of f (x) (1> -1)
