Need help trying to find a linear equation, tried so many things and i still cant figure it out....pleas ehelp?

city growth and the number of burglaries are related by a linear equation. records show that 575 burglaries were reported in a year when the local population was 77000 and that the rate of increase in the number of burglaries was 1 for every 100 residents. using the variables p for population and b for burglaries write an equation for burg vs pop in slope intercept form that police can use to predict future statistics.
