Question

The graph of a proportional relationship passes through (12, 16)

and (1, y)
. Find y

Answer 1

Since X=12/12=1

Y must be divided by same number, 12, thus
y=16/12=1 1/3 or 1.33

Answer 2

Answer: The value of y is
`(4)/(3)`.

Step-by-step explanation:

It is given that the graph of a proportional relationship passes through (12, 16)

and (1, y).

The graph of a proportional relationship means the x and y coordinates are in a proportion k. The equation of the graph is in the form of y=kx. Where k is the proportion factor.

It is given that the graph passing through (12,16).

`y=kx`

`16=k(12)`

`k=(16)/(12)`

`k =(4)/(3)`

So the equation of the line is,

`y=(4)/(3) x`

put x=1.

`y=(4)/(3) (1)`

`y=(4)/(3)`

Therefore, the value of y is
`(4)/(3)`.
