Re: 10 second questions

Hi Howardroark and bobbym,

The solution to 2650 is correct by Howardroark. Well done!
The solutions to 2649 by Howardroark and 2649 and 2650 by bobbym are the distance is

, outside the circle and 2x - 3y = 0.

These are the solutions, as per my opinion.

#2651. If the points (-3,7), (k,1), and (-3,2) are collinear, what is the value of k?

#2652. A point is diametrically opposite to (4,3). Find the other point.
