A line in the xy-plane passes through the origin and has a slope of 1/7. Which of the following points lies on the line? A) (0, 7) B) (1, 7) C) (7, 7) D) (14, 2)
The answer is D. Using the slope equation with the origin at one point and the answer choice as the other point, you can calculate the slope of each answer choice. The only one that gets 1/7 is choice D.
