What is the slope-intercept form of a linear equation?

• y = mx + b, where m is the slope and b is the y-intercept.

• y = ax^2 + bx + c, where a, b, and c are constants.

• y = m(x - b) + b, where m is the slope and b is a point on the line.

• y - b = m(x - a), where m is the slope and (a, b) is a point on the line.
