Please help I need u I have a picture to explain

a10 = 12/7

Step-by-step explanation:

an = a1 + (n-1) d

a10 = 3/7 + ( 10-1) 1/7

a10 = 3/7 + (9) 1/7

a10 = 3/7 + 9/7

a10 = 12/7

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.
