Answer: OPTION D.
Step-by-step explanation:
The formula that is used to calculate the slope of a line is:
Where 
and 
are two points on the line.
In this case the student finds the slope of the line that passes trough these points:
You can notice that she writes in the numerator that:
So she chose the point 
as and the point 
as .
Then 
and 
in the denominator must be:
Therefore, she did not keep the order of the points the same in the numerator and the denominator.
Answer:
2 1/2
Step-by-step explanation:
Turn both fractions into improper fractions, multiply the whole number by the denominator and add the numerator.
4 3/4
4 * 4 + 3 = 19
19/4
2 1/4
2 * 4 + 1 = 9
9/4
Now since she drank 2 1/4 gallons of juice, subtract 9/4 from 19/4.
19/4 - 9/4 = 10/4
Now turn back into a mixed fraction, do this by putting 4 into ten twice and taking the remainder and putting it as numerator:
4 * 2 = 8
10 - 8 = 2
2 1/2
Answer:
y = 3/5x - 1
Step-by-step explanation:
The slope found from counting the units is 3/5, and the y-intercept is -1, hence 3/5x - 1
In the research, it should be noted that this is a Proportion, because worry or not worry is categorical
<h3>What is a proportion?</h3>
A population proportion is the percentage of the population that possesses a particular trait.
For illustration, suppose there are 1,000 people in the population and 237 of them have blue eyes. There are 237 blue eyed people out of every 1,000 people, or 237/1000.
Therefore, it should be noted that this is a Proportion, because worry or not worry is categorical.

#SPJ1
A poll shows that 64% of Americans personally worry a great deal about federal spending and the budget deficit. State whether the parameter of interest is a mean or a proportion.
Add them all together and divide by the number of variables here there are four and the answer is 1.25 or 5/4
