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 β point=(x,y)βpoint=(0,1)
she adds 3 coins per year, then y=1+3x
at x=1, y=1+3(1)=1+3βy=4βpoint=(x,y)βpoint=(1,4)
at x=3, y=1+3(3)=1+9βy=10βpoint=(x,y)βpoint=(3,10)
the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
