Question

Y+4x=0 how can I solve to know if it's a direct variation?

Answer 1

subtract 4x from both sides and you get y=4x

y varies directly with x. When x is 1, y is 1/4. when x is 4, y is 1. when x is 8, y is 2. So on and so on. Sorry if this is confusing. Direct variations is one of my weak points
