Choose the system of equations that matches the following graph:

Picture of coordinate plane with line y equals negative 3 over 7 x plus 1 and line y equals 5 over 7 x plus 9. They intersect at negative 7, 4.

a. 3x + 7y = 7
5x + 7y = −63

b. 3x + 7y = 7
5x − 7y = −63

c. 3x − 7y = 7
5x + 7y = −63

d. 3x − 7y = 7
5x − 7y = −63

Step-by-step explanation:

b. 3x + 7y = 7

b. 3x + 7y = 75x − 7y = −63

Both the equations have common coordinate point (-7,4)

3x + 7y = 7

LHS = 3(-4)+7(4)= -21+28= 7. RHS = 7

Therefore, the equation satisfies.

5x − 7y = −63

LHS = 5(-7)-7(4) = -35-28= -63. RHS = -63

Therefore, the equation satisfies.

the amount you'd have after the work is $1.55
