0-6 Writing Equations in Point- Slope Form

Slope Formula y 1 – y 2 x 1 – x 2 Forms of lines Point-slope form: y – y 1 = m (x - x 1 )

Slope (m) the steepness of a line the rate of change the ratio of change in the y -coordinates to the change in x -coordinates the rise over the run formula

Rate of Change Determine if each function is linear. xy xy Ex 1 Ex
