### Writing Linear Functions

The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept of the line.

The point-slope form of a linear equation is y – y

_{1}= m(x – x_{1}), where m is the slope and (x_{1}, y_{1}) is a point on the line.Use information given about a line to write its equation in these forms. Sometimes it is easier to put it in one form than the other one.
