82, 152, 222, 292, 362. You add 70 each time.
No it is not a negative slope
Answer:
C) Negative
Step-by-step explanation:
<u>Explanation</u>:-
<u>Correlation</u>:-
Correlation is a statistical measure that indicates the extent to which two or more variables fluctuate together
<u>Positive correlation :-</u>
Positive correlation occurs when the two variables of a function move in opposite directions. As the value of 'x' increases ,the Value of 'y' increases. Like wise the value of 'y' decreases, the value of 'x' decreases.
<u>Negative correlation:-</u>
Negative correlation occurs when the two variables of a function move in opposite directions. As the value of 'x' increases ,the Value of 'y' decreases. Like wise the value of 'y' decreases, the value of 'x' increases.
<u>Final answer</u>:-
If the linear correlation between two variables is negative then the slope of the regression line is also positive.

Answer:
y=2x+8
Step-by-step explanation:
Alright so, to find the equation, we need to find the slope first. We can do that by turning the input and output into coordinates.
(1,10) and (2,12)
To find the slope, we do:
Which equals to 2
So right now we can say that the equation is:
y=2x+b
In order to find b, the constant, we just need to plug in the y values and x value of a coordinate:
10=2(1)+b
10=2+b
8=b
So now we can say that the equation is:
y=2x+8
