Answer: Its 1,110
Step-by-step explanation:
1) First, solve one linear equation for y in terms of x .
2) Then substitute that expression for y in the other linear equation.
3)Solve this, and you have the x -coordinate of the intersection.
4)Then plug in x to either equation to find the corresponding y -coordinate.
Answer:
A negative correlation means one variable decreases as the other increases.
