Slope Intercept Form of an Equation - Determining from Graph
This activity will help you develop the connection between the graph and equation of a line (in slope intercept form).
Step 1: Click on one of the lines to show ("Show Line A")
Step 2: type the y-intercept into the "b" box.
Step 3: type the slope into the "m" box (you can write a fraction).
Step 4: If the line "disappears" and turns black, then you have correctly identified the slope and y-intercept! Congrats! If not, try again!
Step 5: Unselect the current line and choose a different one to try.
