Question

The graph of a proportional relationship passes through (12, 16) and (1, y) . Find y

Answer 1

Answer: The value of y is $\frac{4}{3}$.

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).

$y=kx$

$16=k(12)$

$k=\frac{16}{12}$

$k =\frac{4}{3}$

So the equation of the line is,

$y=\frac{4}{3} x$

put x=1.

$y=\frac{4}{3} (1)$

$y=\frac{4}{3}$

Therefore, the value of y is $\frac{4}{3}$.

Answer 2

Since X=12/12=1

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