I think I recall that the formula is f(x) = f(a) + (f(b) - f(a)) * (x - a) / (b - a). I hope I got that right!

This seems similar to a practice question we did last week. I think I need to find the slope first, right?

I remember we practiced linear interpolation in class, but I'm not entirely sure how to set up the formula correctly.
