A coffee shop charges two different prices depending on the size of the cup. The table shows the number of regular-sized coffees and the number of large-sized coffees purchased in the past 3 hours. The total earnings for hours 1 and 2 are given. Each regular-sized coffee costs the same price, and each large-sized coffee costs the same price. The system of equations can be used to represent the situation. Use the drop-down menus to complete each statement.

b. astronomers

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.

it is x equals 3   plese mark me really need it
