You must show ALL work for any credit.

1) Write an equation in slope-intercept form of the

line with a slope of 2 and a y-intercept of –3. Then,

graph the equation.

2) Write the equation 6x + 4y = 12 in slope-

intercept form. Then, graph the equation.

m = _________ m = _________

b = _________ b = _________

3) Write an equation in point-slope form, slope-

intercept form, and standard form for the line that

passes through (2, 3) and is parallel to the line

y = 3x + 1.

4) Write an equation in point-slope form, slope-

intercept form, and standard form for the line that

passes through (–4, –2) and is parallel to the line

y =

12) Andy is purchasing season tickets for the L.A. Lakers games. The ticket package requires a one-time

purchase of a personal seat license costing $600. A ticket to each game costs $70. The cost C(x) in dollars for

Andy for the first season is ( ) , where x is the number of games Andy attends.

a) Find the inverse function

b) What do x and C-1

(x) represent in the context of the inverse function?

c) How many games did Andy attend if his total cost for the season was $950?
