How would you describe the graph of the function in interval 2? Select all that apply.
1 answer:
The graph of the function is missing and so i have attached it alongside the options.
Answer:
B & C are correct.
Step-by-step explanation:
From the attached graph, we can see that at interval 2, the line is falling down and not rising.
This means that the function is decreasing because y is decreasing while x is increasing.
Also, when both x and y are increasing, the slope is positive but when one is increasing and the other is decreasing like we have here, it means the slope is negative.
Thus, the function is decreasing and the slope is negative.

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points through which the line passes:
We find the slope of the line:
Thus, the equation of the line is of the form:
We substitute one of the points and find b:
Finally, the equation is:
