finding the slope using direct variation
I have two questions on my algebra homework that relate to direct variation and I can't remember how to use it.
This is a really confusing question. I really want to understand the steps to doing this problem and finding the answer. Thank you.
Y+11x=0 I need help with solving this problem
If y=6 when x=24, what is the value of x when y=7?
Find x when y=14, if y=7 when x=8.
I know the question uses direct variation to solve it, I'm just not sure how to set up the first calculation (the one before you cross multiply)
The equations are 3x=8y-9 and 3y=9x Thanks
the water pressure on a scuba diver is directly proportional to the depth of the diver. If the pressure on a diver is 22.5 psi when she is 50 feet below the surface, how far below the surface will...
I don't get it
1. x=4.25 , y=1.7 Find y when x=-5 2. X=4.25, y=-3/2 Find y when x=-5 thank you!!
direct variation is when you have the formula y=kx and when it constant
