What is the formula to calculate the gradient of a line passing through two points (x_1, y_1) and (x_2, y_2)?
What is the formula to calculate the gradient of a line passing through two points (x_1, y_1) and (x_2, y_2)?
- Gradient = (y_2 + y_1) / (x_2 + x_1)
- Gradient = (x_2 - x_1) / (y_2 - y_1)
- Gradient = (y_2 - y_1) / (x_2 - x_1) (correct)
- Gradient = (x_2 + x_1) / (y_2 + y_1)
