The figure below 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 10 to positive 10 in increments of 2 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 6, negative 3, and 0, 0, and 6, 3. A shaded right triangle is formed so that its hypotenuse is from ordered pair 0, 0 labeled O to 4, 2 labeled A, one leg is from 0, 0 to 4,0, and the second leg is from 4,0 to 4, 2. Another shaded right triangle is formed with the hypotenuse is from 4, 2 to 6, 3 labeled B, one leg is from 4, 2 to 6, 2, and the second leg is from 6, 2 to 6, 3. Which statement about the slope of the line is true? (5 points) It is fraction 1 over 2 throughout the line. It is 2 throughout the line. The slope from point O to point A is fraction 1 over 2 times the slope of the line from point A to point B. The slope from point O to point A is 2 times the slope of the line from point A to point B.
