In the image, does "log" mean "natural log"?

Hi Skipjack I'm sure it is, I'm looking for the intercept and the gradient. I believe the gradient is 3.7 and the intercept is 4.0?

The intercept shown appears to be at (0, 0.6). These coordinates are the natural logarithms of 1 and 1.822 (approximately). The gradient at the intercept appears to be about 1.7. Note that the graph shown isn't a straight line.
