# Writing Linear Equations Using Slope and Point

y = m(x â€“ x1) + y1

and simplify to the â€œslope-interceptâ€ form of the linear equation:

y = m x + b

We will find that one of three things happen when we seek to write the equation of a line:

1. We are given the slope m and the y-intercept: y = b or (0, b) .

Write: y = m x + b.

2. We are given the slope m and a point (x1, y1).

Write: y = m(x â€“ x1) + y1

Simplify to y = m x + b.

3. We are given two points (x1, y1) and (x2, y2). Find m.
