Question

The graph plots four equations, A, B, C, and D: Line A joins ordered pair negative 6, 16 and 9, negative 4. Line B joins ordered pair negative 2, 20 and 8, 0. Line C joins ordered pair negative 7, negative 6 and 6, 20. Line D joins ordered pair 7, 20 and 0, negative 7. Which pair of equations has (2, 12) as its solution?The graph plots four equations, A, B, C, and D: Line A joins ordered pair negative 6, 16 and 9, negative 4. Line B joins ordered pair negative 2, 20 and 8, 0. Line C joins ordered pair negative 7, negative 6 and 6, 20. Line D joins ordered pair 7, 20 and 0, negative 7. Which pair of equations has (2, 12) as its solution?

Answer 1

Line C is the correct answer

Explanation:

A: y = (-20/3) * x + 56

B: y = (-10/3) * x + (80/3)

C: y = 2 * x + 8

D: y = (27/7) * x - 7

check: line C -- y = 2 * (-7) + 8 = -6 (-7, -6)

y2 = 2 * 6 + 8 = 20 (6, 20)

y3 = 2 * 2 + 8 = 12 (2, 12) .... correct
