Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to StartFraction 7 over 25 EndFraction. She writes the equation y = x + StartFraction 7 over 25 EndFraction. What error is Roni making?

Answer:

[tex]y=\frac{7}{25}x[/tex]

Step-by-step explanation:

For a proportional relationship, we have

y ∞ x.

Let k = constant of proportionality = 7/25

Removing the proportionality sign, we have

y = kx

Therefore, [tex]y=\frac{7}{25}x[/tex]

Instead of [tex]y = x+\frac{7}{25}[/tex]

So, the error is that x should be multiplied by 7/25 and not added.

Answer:

She should have written y = Start Fraction 7 over 25 End Fraction so that y has a constant value.
