Besides checking that two slopes are negative reciprocals, how can you CALCULATE if lines are perpendicular?
(Not looking for "they form 4-90 degree angles.")
Multiply the slopes and see if that equals -1.

Are angles 2 and 6 congruent? Explain. 
No since the transversal is cutting non-parallel lines, we know that angles 2 and 6 are alternate interior angles, but they are not congruent (again, since the lines being cut by the transversal are not parallel.)

Cletus owns a publishing company. It cost $500 to start his business. It costs $6 to print a book. He sells the books for $15 each.
1. Write the equation for the cost of Cletus' business.
2. Write an equation to model how much Cletus makes from each book.
3. Find how many books it will take for Cletus break even.
1. y = 6x+500 (y: $, x: number of books)
2. y = 15x-5x = 10x (y:$, x: number of books)
3. 125 books; 10x=6x+500, solve for x.
