### 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 – y1 = m(x – x1), where m is the slope and (x1, y1) 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.
