Question

1. which of the graphs is most likely to represent the graph of daylight for the month after the spring equinox?

(graphs: a - horizontal line, b - decreasing line, c - line from origin increasing, d - line with positive y-intercept increasing, all with x: days past equinox, y: minutes of sunlight)

Explanation:

After the spring equinox, the amount of daylight (minutes of sunlight) increases as days pass. Let's analyze each graph:

• Graph A: Shows a constant amount of sunlight, which doesn't match the increasing daylight after spring equinox.
• Graph B: Shows a decreasing amount of sunlight, which is incorrect as daylight increases after spring equinox.
• Graph C: Starts at (0,0), but at the spring equinox, there is already a certain amount of daylight (not zero).
• Graph D: Shows a linear increase in minutes of sunlight as days past the equinox increase, which matches the real - world phenomenon of increasing daylight after the spring equinox (since we start with a non - zero amount of daylight at the equinox and it increases over time).

Answer:

D. The graph with a linear increase in minutes of sunlight as days past the equinox increase (the graph labeled D)
