The attached image completes the question.
Answer:
- The part (0, 12000) is constant and the slope is zero
- The part (12000, 38000) is decreasing and slope is negative 0.26.
Step-by-step explanation:
Checking the given graph, we see that
For x = 0 to x = 12,000, the values of y are unchanged. For this, we say it is constant.
The slope here is: 0.85 - 0.85 = 0
For x = 12,000 to x = 38,000, the values of y are decreasing. For this, we say it is negative.
The slope here is: 0.59 - 0.85 = -0.26.

<u>Equation of a line</u>
A line can be represented by an equation of the form
Where x is the independent variable, m is the slope of the line, b is the y-intercept and y is the dependent variable.
We need to find the equation of the line passing through the point (7,2) and is perpendicular to the line y=5x-2.
Two lines with slopes m1 and m2 are perpendicular if:
The given line has a slope m1=5, thus the slope of our required line is:
The equation of the line now can be expressed as:
We need to find the value of b, which can be done by using the point (7,2):
Operating:
Multiplying by 5:
Operating:
Solving for b:
The equation of the line is:
