of proportionality​

Answer 1

$\huge \bold \red {❥answer}$

If you are said x and y are directly proportional you just have to write the equation y=kx, find the k. (if y is directly proportional to x, this means x is also directly proportional to y. so if y=kx then we can say x=k'y, where k'=1/k.)

pls markme as brainsist

Step-by-step explanation:

If you are said x and y are directly proportional you just have to write the equation y=kx, find the k. ... (if y is directly proportional to x, this means x is also directly proportional to y. so if y=kx then we can say x=k'y, where k'=1/k.)
