Answer:
The second choice: it is -1/2 through the line
Step-by-step explanation:
First, let us calculate the slope of the line. Note that points A, B and O lie on the same line, and therefore, the lines they form have the same slope (slope of AB is the same as the slope of BO).
The slope of the line is
Hence, the slope of the line is -1/2 and therefore the second answer choice is the correct answer!
