3x + y = -3
-2x + y = 7
Use elimination method
Subtract both equations
5x = -10, x = -2
Plug in -2 for x (any equation)
3(-2) + y = -3
-6 + y = -3
y = 3
Solution: x = -2, y = 3
Or as a coordinate: (-2, 3)
Answer:
<u><em>Negative Correlation</em></u>
The variable x - value increases as y- value decreases is called negative correlation.
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Negative correlation:-
The negative correlation is a relation between two variables such that they are part of a function in which depends and independent variables move in different directions in terms of value.
<u><em>Positive correlation</em></u>
The variable x - value increases as y- value increases is called positive correlation.
<u><em>Negative Correlation</em></u>
The variable x - value increases as y- value decreases is called negative correlation.
<u><em>No correlation </em></u>
There is no pattern between two variables
there is no connect between two variables is called No - correlation
C is 2 because you have to move the 5 so you add 5 to 13 which is 18 then divide both sides by 9 so it's 2
