How it works ?
Note the linear equation written in standard form (upper left corner).
For slope, enter an EXACT RATIO VALUE (not a rounded approximate value).
For x-intercept, simply enter the x-coordinate of the graph’s x-intercept. You may need to enter this value as an EXACT RATIO. If this is the case, do so. (Do not use a rounded approximate value).
For y-intercept, simply enter the y-coordinate of the graph’s y-intercept. You may need to enter this value as an EXACT RATIO. If this is the case, do so. (Do not use a rounded approximate value).
Be sure to click the “Check Graph” checkbox to check your graph (afterwards)!
