Question

amina opens a savings account. she starts her savings account with 20 dollars she got as a gift for her birthday. each week she adds 15 dollars to her account. this graph represents the amount in the account, y, after x weeks. you can write the vertical intercept as the point (0, 20), or as a single number. since the x - coordinate of the vertical intercept is always 0, you can represent the vertical intercept as just the y - coordinate of the point (0, 20). what’s another way we can write the vertical intercept? the line crosses the vertical axis at the point (0, 20). the vertical intercept is \boxed{}.

Explanation:

The vertical intercept is the initial amount in the account, which is the y-value when x=0. It can also be described as the starting value or the constant term in the linear equation for the account balance. The linear equation for this scenario is $y=15x+20$, where 20 is the vertical intercept (the constant term).

Answer:

We can write the vertical intercept as the constant term in the linear equation representing the relationship, which is 20, or describe it as the initial account balance of 20 dollars. The numerical value for the blank is 20.
