Question

7
Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to 25
7
She writes the equation Y = X+ 25. What error is Roni making?
7
She should have written Y =-X+ 25 so that x and y have a constant sum.
7
She should have written XY - 25 so that x and y have a constant product.
7
She should have written Y = 25% so that x and y have a constant quotient.
7
She should have written Y = 25 so that y has a constant value

Answer 1

Answer:

She should have written Y = 25X

Step-by-step explanation:

We are told that Roni writes the equation Y = X + 25.

Now, since she wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to 25, it means that she shouldn't have added 25 to X but instead multiply it with X to get;

Y = 25X
