Unit 6: Linear Functions

You should now know how to find the Rate of Change/Slope (m) and the Initial Value/Y-Intercept (b) from graphs, tables, ordered pairs, and words.

  1. Find m – use rise/run,  slope formula, or change in y over change in x
  2. Find b- look for y-intercept  on graph, find where x is 0 on the table (count backwards if needed), or solve for b in an equation with y, m, and x substituted in
  3. Write your equation in slope intercept form: y = mx + b
