Question

Help! For each function, determine whether y varies directly with x.if so, identify the constant variation

question 4y-7x=0
then i put 4y=7x
what to do next?

Answer 1

we are given with the expression 4y - 7x = 0. this is equal to 4y = 7x or y = 7/4 x. In this case, y is directly proportional to x where the constant of proportionality is equal to 7/4. When x increases, the value of y also increases, and vice versa.
