Explain how you can determine the slope of a line using two points on a Cartesian plane.

By calculating the rise (change in y) over the run (change in x) between the two points.

Describe a real-world example of a negative slope.

A snowboarder sliding downhill.

3 key concepts

1
A slope describes the steepness of a line.
2
Slope, represented by the letter m, is calculated as rise over run, which is the change in y over the change in x.
3
A line that goes up from left to right has a positive slope, a line that goes down from left to right has a negative slope, a horizontal line has a zero slope, and a vertical line has an undefined slope.
