x = 8 and y = 10

Step-by-step explanation:

The given equations are :

2x -y  = 6 (1)

-9x + 3y = -42 (2)

Multiply eqation (1) by 3.

6x - 3y = 18 (3)

Adding equation (2) and (3).

-9x + 3y + 6x - 3y = -42 +18

-3x = -24

x = 8

Put the value of x in equation (1).

2(8) -y  = 6

16 - 6 = y

y = 10

Hence, the values of x and y are 8 and 10 respectively.

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.
