C.
y = 2x

1 answer

To write the equation of the line \( y = mx \) that describes the proportional relationship shown in the graph, we need to determine the slope \( m \).

The options given are:

A. \( y = \frac{1}{2}x \)
B. \( y = x \)
C. \( y = 2x \)

Since I cannot see the graph, I will explain how to choose the right equation based on the slope.

  1. If the line rises at a 45-degree angle, the slope \( m = 1 \) and the equation is \( y = x \) (option B).
  2. If the line rises less steeply, say half as steep, then the slope \( m = \frac{1}{2} \) and the equation is \( y = \frac{1}{2}x \) (option A).
  3. If the line is steep, meaning it rises rapidly, then the slope \( m = 2 \) and the equation would be \( y = 2x \) (option C).

Please check the graph to determine the slope of the line, and choose the corresponding option.
