Answer:

y=75x+25

Explanation:

We know that rowan opens the savings account with $25, so the y-intercept (or b) is 25 as this is what he starts with at 0 months. For each additional month, he saves $75, so we can set the slope to $75 and let x be the number of months. This linear equation will find the balance in Rowan's savings account
