The spread of a disease in a community is modelled by the following differential equation:(adsbygoogle = window.adsbygoogle || []).push({});

dy/dx = 0.2y - 0.02x where y is the number of infected individuals in thousands, and x the time in days.

1) Show the equation that for the family of 'curves' in the x-y plane for which dy/dx is a constant, is of the form y=mx+c.

How can I do this please?
