Question

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 30 to positive 30 in increments of 6 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 24, negative 4, and 0, 0, and 24, 4. A shaded right triangle is formed so that its hypotenuse is from ordered pair 0, 0 labeled as O to 12, 2 labeled as A, one leg is from 0, 0 to 12,0 and the second leg is from 12,0 to 12, 2. Another shaded right triangle is formed with the hypotenuse from 12, 2 and 18, 3 labeled as B, one leg is from 12, 2 to 18, 2 and the second leg is from 18, 2 to 18, 3.
Which statement about the slope of the line is true? (1 point)

a
It is fraction 1 over 6 throughout the line.

b
It is 6 throughout the line.

c
The slope from point O to point A is fraction 1 over 6 times the slope of the line from point A to point B.

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