\frac{\mathrm{d}}{\mathrm{d}x}(-0.25x+0.8)
Combine 0.15x and -0.4x to get -0.25x.
-0.25x^{1-1}
The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.
-0.25x^{0}
Subtract 1 from 1.
-0.25
For any term t except 0, t^{0}=1.
-0.25x+0.8
Combine 0.15x and -0.4x to get -0.25x.
