You need to find the slope of a line which you find by picking two points then subtracting one y value from the other and subtracting the corresponding x values from each other (ex. (16,4) and (3,6) 4-6/16-3= -2/13. So -2/13 is the slope) for the second question about negative or positive correlation it means if the y value increases does the x value increase as well(or vice versa)? if so then its a positive correlation however if when the y value increases the x value decreases (or vice versa) its a negative correlation . If the dots are just all over the place its no correlation

I can only help you with the second one. It is a positive correlation because it is going upwards. Good luck with the first one!

ehidna [41]

Shawna got 16 items correct

Step-by-step explanation:

To find the percentage of answers or part of total answers we multiply the fraction with the total number of items.

Given

Total items on test = 20

Correct items fraction = 4/5

Then,

Correct\ items=\total\ items * \fraction\ of\ correct\ answers\\= 20 * \frac{4}{5}\\=\frac{80}{5}\\=16

Shawna got 16 items correct

Nataliya [291]

 Answer: Y-48

<span>If the median of the values in the data set is Y, it means that Y is the value in the middle of the data set. If 48 will be deducted from each of all values in the data set including Y, then the median of the resulting value will be Y-48. </span>
