Question

the ratio of adults to students on a field trip is 1 to 2. which graph shows the relationship between the number of adults, x, and the number of students, y.

Explanation:

Step1: Determine the relationship

The ratio of adults (\(x\)) to students (\(y\)) is \(1:2\), so the equation is \(y = 2x\).

Step2: Check the graph

For graph A, when \(x = 1\), \(y = 2\); \(x = 2\), \(y = 4\); \(x = 3\), \(y = 6\); \(x = 4\), \(y = 8\). These points satisfy \(y = 2x\).

Answer:

A. The graph with points (1,2), (2,4), (3,6), (4,8) showing \(y = 2x\) (the graph labeled A)
