Describe and correct the error made in deciding whether (-5, 4) is a solution of 2x+3y= -7.
2x+3y= -7
2(4)+3(-5)= -7
8+(-15)= -7
-7= -7√

List four solutions of the equation.
y= -2x+5
16x+24=y
y=½x-1

Write the equation in function form. Then list four solutions of the equation.
x+y=8
33= -3x+y
4y=8x+12
12=3x+y
-32=4x-12y
-6y+3x=9

Your skateboard club decides to replace each club member's wheels for a competition. A set of wheels sells for $24 plus a $14 shipping and handling cost.
A. Use the equation C=24n+14 where C is the total cost in dollars and n is the number of sets of wheels ordered. What is the total cost of 4 sets of wheels?
B. The total cost of your club's order is $182. How many sets of wheels are purchased?
C. Suppose your club doubles the order. Will the total cost be $364($182*2)? Explain.
