The rate of change is -2
Step-by-step explanation:
The slope-intercept form of a linear equation is y = m x + b, where
- m is the slope which represents the rate of change
- b is the y-intercept which represent the initial value (value y at x = 0)
∵ y = -2x - 1
- The equation in the slope-intersect form, compare it with
the form above
∴ m = -2
∴ b = -1
∵ m represents the rate of change
∴ The rate of change is -2
∵ b represents y at x = 0
∴ The y-intercept is -1
The rate of change is -2

Step-by-step explanation:
Answer:
The answer should be: B
I think it's B because there are 2 cups of water (2c) and 7 bottles of water (7w) which costs $16 so that would be 2c +7w=16. Also for the other one, it's 3 cups (3c) and 8 bottles of water (8W) and the cost is $19 so that would be
3c + 8w =19

Using linear functions, it is found that the two plans cost the same for 5000 minutes of calling.
<h3>What is a linear function?</h3>
A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
For Plan A, the cost is of $25 plus an additional $0.09 for each minute of calls, hence the y-intercept is 
, the slope is of 
, and the function is:
For Plan B, the cost is of $0.14 for each minute of calls, hence the y-intercept is 
, the slope is of 
, and the function is:
The plans cost the same for x minutes of calling, considering that:
The two plans cost the same for 5000 minutes of calling.
