Zoe the goat is tied by a rope to one corner of a 15 meter‑by‑25 meter rectangular barn in the middle of a large, grassy field. Over what area of the field can Zoe graze if the rope is: A)10 meters long? B)20 meters long? C)30 meters long? D)Zoe is happiest when she has at least 400 `m^{2}` to graze. What possible lengths of rope could be used?

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
