Question

if x is directly proportional to y and x =4.5 when y =3 find an equation connecting x and y

Answer 1

Answer:

A / Q : -

x ∝ y ; Let's the constant is K

=> x = K y

&

x = 4.5 at y = 3

Therefore ,

4 . 5 = K × 3

=> K = 4.5 / 3 = 1.5

So , Equation Connecting x & y will be : -

=> x = 1.5 y
