Sarah wants to find the output value that produces the same output for the function represented by the tables? what is the input value that produces the same output value in both charts? -2 -1 1 2

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

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.
