What set of number does -2/5 belong to

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

i believe that the answer is

b. y-1=-2(x-4)

hope this !
