Write the equation of the line in fully simplified slope-intercept form.

y=-1/2x-1

Step-by-step explanation:

the slope intercept form is y=mx+b

m=slope

b=y intercept (where the line crosses the y axis)

to find slope you do rise over run or rise/run

the rise of you slope is -1, and the run of your slope is 2, meaning your slope is -1/2

the line crosses the y axis at point -1

plug what you find into the slope intercept form, and you get y=-1/2x-1

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
