A teacher graphs a system of equations using the lines shown and asks four students to write down the coordinates representing the solution to the system. Based on the graph, which student’s ordered pair represents the solution to the system of equations?

A. (3, 2)

B. (2, 3)

C. (0, 5)

D. (0, -1)

whats the question?

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
