The figure shows a line graph and two shaded triangles that are similar:

A line is shown on a coordinate grid. The x-axis values are from negative 35 to positive 35 in increments of 7 for each grid line. The y-axis values are from negative 5 to positive 5 in increments of 1 for each grid line. The line passes through the ordered pairs negative 28, negative 4, and 0, 0, and 28, 4. A shaded right triangle is formed so that its hypotenuse is from ordered pair 0, 0 labeled as O to negative 14, negative 2 labeled as A, one leg is from 0, 0 to 0, negative 2, and the second leg is from 0, negative 2 to negative 14, negative 2. Another shaded right triangle is formed with the hypotenuse from negative 14, negative 2 to negative 21, negative 3 labeled as B, one leg is from negative 14, negative 2 to negative 14, negative 3, and the second leg is from negative 21, negative 3 to negative 14, negative 3.
Which statement about the slope of the line is true? (1 point)

Group of answer choices

It is 7 throughout the line.

It is fraction 1 over 7 throughout the line.

The slope from point O to point A is fraction 1 over 7 times the slope of the line from point A to point B.

The slope from point O to point A is seven times the slope of the line from point A to point B.
