It's negative correlation because the dots are dropping in value.
<em>A positive correlation starts in the bottom left corner and rises to the top right. While a negative correlation starts at the top left corner, and drops in value. No correlation has dots randomly placed throughout the graph and a line can't be drawn to represent the correlation. </em>
When multiplying a number by a variable the number is written first and then the variable. It can be represented like this: 4(x). If you simplify that you get 4x.
