Possibly a silly question but is their A distinct way of finding out whether the data shows it’s ax^n or kb^x?

Sorry I'm a bit lost and confused. Near the end you say the y intercept = log10a but why is that?

I calculated the most accurate line of best fit using the line of regression formula,
which was; Y = 2.500402954X - 0.2528445153. I used these values to obtain an equation of the curve - y =
When plugging values of x from the original data back into this equation, every single result was exact to 1.d.p.
Would the mark scheme reward full marks for this method providing you plot the equation of the regression line as asked?

How would u know the scale to use for the plotting

Is there a way of finding exact values of a and n? (assuming data is accurate)
