Question

the graph shows the relationship between the water level of a pond and the number of days since it rained. which statement best describes the y - intercept? a the water level increased by 0.5 feet each day b the water level decreased by 2 feet each day c it took 6 days for the pond to dry up d the initial water level was 12 ft

Explanation:

The y-intercept of a linear graph is the value of \(y\) when \(x=0\) (number of days = 0, the starting point). On the graph, when \(x=0\), the water level (y-value) is 12 ft, which matches option D. Option A/B describe slope (rate of change), not y-intercept. Option C refers to when \(y=0\), which is the x-intercept, not y-intercept.

Answer:

D. The initial water level was 12 ft
