Question
A balloon filled with helium is released from a height of 6 feet. The balloon rises at a constant rate of 3 feet per second. Which equation represents the height of the balloon (y), x seconds after it was released.
y = 3x + 6
y = 6x + 3
x = 3y + 6
x = 6y + 3 <--?
Using your equation from question #3, what is the height, in feet, of the balloon after 10 seconds?
36 inches
36 feet
63 feet<--?

you've got x and y switched
... and the rate of ascent is the slope
the right equation will give the right answer
