Which ordered pair is a solution to y = 4.5x + 20?

X = 5, y = 4.5(5) + 20 = 42.5 (5,  42.5)
so (5,40) is not a solution

x = 7, y = 4.5(7) + 20 = 42.5  (7,  51.5)
so (7,52) is not a solution

x = 10, y = 4.5(10) + 20 = 65  (10,  65)
so (10,25) is not a solution

x = 12, y = 4.5(12) + 20 = 74  (12,  74)
so (12, 74) is  a solution

answer
D (12, 74)
