8, - 3

Step-by-step explanation:

one number is x, the other is y

x  = 1/3y + 9

=> (1/3y + 9 + y) × 3 = 15

=> y + 27 + 3y = 15

=> 4y = 15 - 27

=> 4y = - 12

=> y = - 3

x  = 1/3(- 3) + 9 = 8

step-by-step explanation: yes

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.
