Question

representing proportional relationships
proportional relationships can be represented by
the equation $y=kx$
$y = 3x$
$y = -1.5x$
$y = \frac{2}{3}x$
$k$ is sometimes called a unit rate or rate.
for example: $y = 25x$
if we are talking about getting paid $25 an hour
for a job, $25 represents rate of pay for one day.
what is the value of $k$ in the equation: $y = 7x$

rewatch

Explanation:

Step1: Identify proportional form

Proportional relationships follow $y=kx$, where $k$ is the constant of proportionality.

Step2: Match given equation to form

The given equation is $y=7x$. Comparing to $y=kx$, the coefficient of $x$ is $k$.

Answer:
