b. What does the slope represent?
c. What type of slope is represented by the graph?
d. What is the -intercept?
e. Define the variables x and y.
f. Write a function, f (x), that represents this situation.

Answer 1

Answer:

The slope is 2

The slope represents  how much it costs per visit the pool.

We have a positive slope when lines go  from bottom left to top right

The y intercept is where we cross the y axis which is 4.

x is the  number of visits to the pool

y is the  total cost in dollars

f(x) = 2x+4

Step-by-step explanation:

To find the slope we take two point ( 0,4) and (1,6)

and use the formula

m = (y2-y1)/(x2-x1)

  = (6-4)/(1-0)

 m= 2/1

The slope is 2

It represents  how much it costs per visit the pool.

We have a positive slope when lines go  from bottom left to top right

The y intercept is where we cross the y axis which is 4.

x is the  number of visits to the pool

y is the  total cost in dollars

f(x) = mx+b  where m is the slope and b is the y intercept

f(x) = 2x+4
