$\frac{1}{2}\int_{-9}^{0}-\left(y+9\right)dy$
Learn how to solve definite integrals problems step by step online. Integrate the function (-(y+9))/2 from -9 to 0. Take the constant \frac{1}{2} out of the integral. Divide 1 by 2. The integral of a function times a constant (-1) is equal to the constant times the integral of the function. Expand the integral \int\left(y+9\right)dy into 2 integrals using the sum rule for integrals, to then solve each integral separately.
