Choice C
Step-by-step explanation:

Hope this helps!
X ·2 = 12x - 15
2x = 12x - 15
2x + (-12x) = (12x - 15) + (-12x)
Result: x = 3/2
Answer:
Y = Mx+C (General equation of a straight line)
Step-by-step explanation:
From the data given above, we could deduce that the data has two coefficients (X and Y). The numbers could be used to generate equation of a straight line.
E.g 2x+4 = 5y which is equivalent to
Mx+C = Y
Where C is the constant.
Answer:
5.25
Step-by-step explanation:
15/10=1.5
9*1.5=13.5
13.5-3=10.5
