Question

I’m confused on if I have to multiple decimals or not.

Answer 1

x and y varies directly and the equation will be: y=480.x

Step-by-step explanation:

We need to write the equation to represent the relationship between x and y

We can find if x and y varies directly or indirectly.

Checking if x and y varies directly

if x and y varies directly then y=kx or y/x = k then k is constant

if x=2 and y=960 then k is:

k=y/x= 960/2 = 480

if x=2 and y=960 then k is:

k=y/x = 1440/3=480

if x=2 and y=960 then k is:

k=y/x= 2880/6=480

if x=2 and y=960 then k is:

k=y/x=3840/8 = 480

Since y/x = 480 for every value of y and x in the table, so x and y varies directly and the equation will be:

y= kx

y=480.x
