From the graph, the coordinates of the cross that represent this car on the graph are ( 8, 2100).
<h3>What is the correlation coefficient?</h3>
The correlation coefficient is a measure of how similar two datasets are acting.
When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated. 
One data increases and other data starts to decrease in the opposite direction.
When the correlation coefficient comes out below 0, values are negatively correlated.
The correlation shown by the graph is negative.

Answer:

Step-by-step explanation:
Let: 

This is and exact equation, because:

So, define f(x,y) such that:

The solution will be given by:

Where C1 is an arbitrary constant
Integrate  with respect to x in order to find f(x,y):
 with respect to x in order to find f(x,y):

Where g(y) is an arbitrary function of y.
Differentiate f(x,y) with respect to y in order to find g(y):

Substitute into 

Integrate  with respect to y:
 with respect to y:

Substitute g(y) into f(x,y):

The solution is f(x,y)=C1

Solving y using quadratic formula:

 
        
             
        
        
        
Answer:
5x+9y=-16
Step-by-step explanation:
here is my work although I am not 100 percent sure I am right because,I am learning the same thing as you
-6+1 over 4+5
y+1=-5/9(x+5)
y+1=-5/9x-25/9
y=-5/9x-16/9
5/9+y=-16/9
5x+9y=-16
