Question

amount consumed each trial vs. time (s)
how many
items are
consumed at
t = 4 s?
6 3
8 0

Explanation:

Step1: Locate t = 4 on x - axis

Find the position of \( t = 4 \) seconds on the horizontal (time) axis of the graph.

Step2: Find corresponding y - value

From \( t = 4 \) on the x - axis, move vertically to the line in the graph, then horizontally to the y - axis (amount consumed). The y - value at \( t = 4 \) is 6.

Answer:

6
