# Physics IA (how to plot a straight line graph from negative curve)

## Recommended Posts

Hi,

So from my experimental data I have plotted a negative curve and my best fit has an equation y = (0.5/x) + 2. Now in order to do max/min lines and find the uncertainty in the gradient, I have to somehow make this a straight line graph. What do I have to plot against what to make it a straight line?

Thanks

Plot a new graph but with the X values squared. If that doesn't work then do the same thing but with the Y values squared instead. (Sorry I forgot which one you do for a negative curve)

Hello sir, so y +0.5/x, is the same thing as y =0.5x^-1,

You must change your x values to 1/x! and then plot y against 1/x!

For example if you have a value of 10, change it to 0.1

My work here is done.

Good day sir.

Couldn't you just plot the X axis as 1/x? This would make your equation 0.5(1/x)+2 but since your axis values are 1/x already it would make it a straight line O.o
