For the example problem: Length of shadow depends on the height of the flagpole. The relation is direct. Also, I know y depends on x.

This is given in the directions:

"If increasing one variable causes the other to increase, this is called a direct relation.

If increasing one variable causes the other to decrease, then this is called an inverse relation."

 

If you increase the height of the flagpole, the length of the shadow will increase. Relation is direct.

 

If you increase the weight of cut, the cost of the cut diamond will increase. Relation is direct.

 

If you increase the weight of runner, the time to run 2 miles will increase. Relation is direct.

 

If you increase speed of internet connection, time to load a large file will decrease. Relation is inverse.

(Even in this example, the time to load a large file depends on the speed of internet connection.)

 

If you increase the HP of a motorcycle engine, the acceleration of cycle will increase. Relation is ___.

 

If you increase the practice time, the ability to play a guitar will ____. Relation is ___.

 

Do you know the answer to the last ones? smiley

Thank you so much for your help! Are they both direct?
