Agraph has a constant of proportionality of 2.54. let y represent centimeters and x represent inches. what is the unit rate of the relationship? enter your answer, as a decimal, in the box

2.54 is the rate of the given equation.

Step-by-step explanation:

Here x represents cm and y represents inches,

So we can take x as independent variable and y as dependent variable.

Then, By the definition of proportionality,

y = k x

Where k is the constant of proportionality.

And, Here k = 2.54

Thus, the equation of line is,

y = 2.54 x

since, rate of the equation is the slope of the line.

And, the general equation of line

y = m x +c

Where, m is the slope of the line.

By comparing the equation of line y = 2.54 x  with this.

We get, slope of the line, m = 2.54
