graph the following linear equations and determine the correct classification:
L1:y=x+5 and L2:y=2x+1

a flagpole casts a shadow 10 ft. long if a man 6 ft. tall casts a shadow 4 ft. long at the same time of day, how tall is the flagpole.

First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.
Let x = length of flagpole.
x/10 = 6/4
Solve for x.
