Answer
y = -3x + 2
Work Step by Step
To create a function, you need a point and a slope. This question tells us the derivative of the function f is -3, so this is our slope. Our point is (0,2) as indicated by f(0) = 2.
Putting this into point-slope form gives us y-2 = -3(x-0)
This can be simplified to y-2= -3x
Which can be rewritten as y = -3x+2
