Hey everyone! Can anybody help me with this math problem involving graphs? I would be very grateful if you could!

============================================================

Explanation:

All direct variation graphs are straight lines that pass through the origin (0,0). This particular line also passes through (2,5). Draw a straight line through both points and you'll see the line passes through (4,10) as well. Check out the graph below. The equation of the direct variation graph is y = (5/2)x which is the same as y = 2.5x

Note that going from (2,5) to (4,10) has us double each coordinate. So another point on this line would be (3,15) as I've tripled the original coordinates. You can generate as many points as you like in this fashion.

Or you could note that y/x = 5/2 = 2.5 for the first point given and y/x = 10/4 = 2.5 for the answer point. This applies to any point on the line that isn't the origin.
