Question

The graph of a proportional relationship passes through the points (15,3) and (5,y). Find y

Answer 1

simple question answer is (15,3) and (5, y=1)

Answer 2

The value of y is 1.

Step-by-step explanation:

It is given that the graph of a proportional relationship passes through the points (15,3) and (5,y).

We need to find the value of y.

$y\propto x$

$y=kx$              .... (1)

Substitute x=15 and y=3 in the above equation.

$3=k(15)$

Divide both sides by 15.

$\dfrac{3}{15}=k$

$\dfrac{1}{5}=k$

Substitute k=1/5 in equation (1) to find the equation of proportional relationship.

$y=\dfrac{1}{5}x$

Substitute x=5 in the above equation.

$y=\dfrac{1}{5}(5)=1$

Therefore, the value of y is 1.
