Answer:

  (1.43, 1.87)

Step-by-step explanation:

The formula for the incenter requires we know the lengths of the sides of the triangle. These are found using the distance formula.

  BC = √((4-3)^2 +(5+1)^2) = √37

  AC = √((-4-3)^2 +(2+1)^2) = √58

  AB = √((-4-4)^2 +(2-5)^2) = √73

Then the incenter is ...

  (A(BC) +B(AC) +C(AB))/(BC +AC +AB)

  ≈ (6.08276(-4, 2) +7.61577(4, 5) +8.54400(3, -1))/22.2425

  ≈ (1.42808, 1.87480)

Rounded to hundredths, the incenter is (1.43, 1.87).
