Final answer:
The vertical intercept or y-intercept of the non-proportional relationship graph, given the information provided, is 50. This is consistent with the understanding that a y-intercept represents where a line crosses the y-axis when x is 0.
Step-by-step explanation:
The question asks for the vertical intercept of a non-proportional relationship between balance and deposits. Considering the provided information, which indicates that the line's y-intercept is 50, the vertical intercept on the y-axis would be 50.
Also, understanding the slope and its direction is vital; a negative slope indicates that as the x-value increases, the line descends on the graph, while a positive slope means the line ascends. Therefore, given that the y-intercept is at 50, regardless of the line's slope being positive or negative, the initial value remains the same, thus confirming the vertical intercept or the y-intercept as 50.
