From the four graphs presented, it is expected the only one with a negative correlation coefficient is the third graph or graph c.
<h3>What is a negative correlation?</h3>
This occurs when the two variables analyzed go in opposite direction, which means one increases and the other decreases.
<h3>How is this represented in a graph?</h3>
In a graph, a negative correlation coefficient is related to a negative slope.
This negative slope can be seen in the third graph or graph C.

The answer is The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and <span>5x + 5y = 50 is (8, 2)
Harry's money is $ 32
He said that he spent ALL of his money buying 3 Notebooksx and 4 cards y, so the equation that represent this is </span>
3x + 4y = 32 .
He said that HE IS SHORT $18 if he wants to buy 5 notebook x and 5 cards y,
So the equation that represent this is
5x + 5y = 32 + (18)
5x + 5y = 50
And (8,2) is the only one that fit in both equation/
