hi, i want to find the value of x where y is zero from the linear plot which is plotted using data points exclusive of the desired x.

[Bob Thompson]

Do you know the slope of the line? If so, just solve for the y value. Also, just from looking at the plot, that point is (0,0).

[Adam Danz]

You could use this intersection function and provide the coordinates of your blue line and the coordinates of a line at y=0.
