For a linear function f, f(2) = -2 and f(3) - f(9) = 15. Here’s the question: What are the intercepts of the graph of f?

I would start with assumption:

f(x) = m * x + c

Please tell us exactly what have you tried and where are you stuck?

The slope is given to you indirectly. Think about how you can get the slope from here. Rise/run
