Key concepts
3 concepts
- 1
The slope of a line is the ratio of the vertical change to the horizontal change, which can be found using the formula m = (y₂ - y₁) / (x₂ - x₁).
- 2
When calculating slope, remember that subtracting a negative number is the same as adding a positive number, and the resulting fraction should always be simplified.
- 3
If the slope of a line is positive, the line moves uphill from left to right; if the slope is negative, the line moves downhill from left to right.
