What's the Formula for Slope?
Slope? Does that mean the angle of the line on the graph? Yes, but it's not referred to as an angle on the graph. The slope of the line means how much does the line move up or down in comparison as to how much it moves left or right. So,...

What's Negative Correlation?
If the y-value decreases as the x-value increases then you have a negative correlation. Meaning that the line-of-fit has a negative slope.
