Answer:
x = 6
Step-by-step explanation:
12x+252=324
Subtract 252 from each side

12x =72
Divide each side by 12
12x/12 = 72/12
x =6

Answer:
line c
Step-by-step explanation:
The graph representing a direct variation equation always passes through the origin. This could be graphs (a) or (c)
given y =
x
with slope = 
Since graph (a) slopes down from left to right it's slope is negative
Hence it is not graph (a) as the slope given in the equation is positive.
Hence the required graph is (c)
