The equation \( y - y_1 = m(x - x_1) \) is known as the **point-slope form** of a linear equation. In this form:

- \( m \) represents the slope of the line.
- \( (x_1, y_1) \) is a specific point on the line.

To write an equation in this form, we need the slope \( m \) and any point on the line \( (x_1, y_1) \).

Therefore, the correct statement about the equation is:

**This is point-slope form, and we need the slope m and any point on the line (x1, y1) to write an equation in this form.**
