Since y varies directly as x, you know that y=245 and x=7 can be used as a proportion, 245/7. When you multiply this proportion to 9, you get 315. This is the value of y when x=9.
y=315

Answer:
EASY DUBS:
Step-by-step explanation:
2*x-((1/4)*y) = 1 // - 1
2*x-((1/4)*y)-1 = 0
2*x+(-1/4)*y-1 = 0
2*x-1/4*y-1 = 0 // + -1/4*y-1
2*x = -(-1/4*y-1) // : 2
x = (-(-1/4*y-1))/2
x = (1-(-1/4*y))/2
x = (1-(-1/4*y))/2
