Answer:

Equation of direct variation is : \mathbf{y=5x}

Step-by-step explanation:

We are given: x= 5 and y=25

We need to write equation of direct variation.

The formula for direct variation is: \mathbf{y=kx}

So, if y=25 and x=5, k will be:

y=kx\\25=k(5)\\k=\frac{25}{5}\\k=5

So, equation of direct variation is : \mathbf{y=5x}
