Arrange the circles (represented by their equations in general form) in ascending order of their radius lengths, x^+y^-2x+2y-1=0, x^+y^-4x+4y-10=0, x^+y^-8x-6y-20=0, 4x^+4y^+16x+24y-40=0, 5x^+5y^-20x+30y+40=0, 2x^+2y^-28x-32y-8=0, x^+y^+12x-2y-9=0.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
