Answer:
A line that represents a proportional relationship passes through the origin, so these data are directly proportional.
Step-by-step explanation:
2.5y + 3x=7 (1st)
5x - 2.5y = 5 re-write -2.5y + 5x = 5 (2nd)
2.5y + 3x=7 (1st)
-2.5y + 5x = 5 (2nd)
---------------------------add
8x = 12
x = 12/8 = 1.5
2.5y + 3x=7
2.5y + 3(1.5)=7
2.5y = 7 - 4.5
2.5y = 2.5
y = 1
answer
solution (1.5 , 1)
