It should be d. , Because if you take the equation 3x+y=9, and make it slope intercept form, it would be y= -3x+9. -3 is the slope, and 9 is the y intercept. D is the answer.
so you take the average of the x coordinates and the average of the y coordinates to get the midpoint like this
The answer is 40*8.50 * 7.65/100 = 26.01 and that's your answer
Let's take a peek of each term, to be specific, the exponent of the variables only, to see what degree each term is

so...which term has the highest degree? well, that one, is the degree of the polynomial
