Answer 1

Answer:

Direct proportionality states that:

if $y \propto x$

then;

$y = kx$ .....[1] where, k is the constant of proportionality.

As per the statement:

The graph shown a proportional relationship.

From the graph we have;

$(\frac{1}{4}, \frac{3}{8})$

⇒$x = \frac{1}{4}$ and $y = \frac{3}{8}$

Substitute these values in [1] we have;

$\frac{3}{8} = k \cdot \frac{1}{4}$

Multiply both sides by 4 we have;

$\frac{3}{2} = k$

or

$k = \frac{3}{2}$

Therefore, the constant of proportionality is, $\frac{3}{2}$ or 3: 2
