Mass-Luminosity relation

Most stars (Main sequence) generate light through the same mechanism. Because of this, there is an empirical relation between their mass, M, and their Luminosity, L. This relation could be written in the form $$L/L_{sun} = (M/M_{sun})^\alpha$$ This relation is shown in the log-log diagram below. Find the value of ${\alpha}$ and round it to the nearest integer.
