Semester 1 Review - MAT-MS-ALGHON

Samuel and Joyce both bought CDs. Samuel bought 3x CDs and Joyce bought 2x-1 CDs. Part A: If each CD had a regular price of $18 and a discount of $2, then which expression would show the amount of discount for all of their CDs?

• 5x – 1

• 2(4x)

• 2(5x – 1)

• 16(6x)

• 2(5x – 1)

Simplify each expression.

Match the solution type to the system of equations:

• the same line

• infinite solutions

• one solution

• parallel lines

• intersecting lines

Define the domain and range of the relation. {(2,3),(0,3),(4,2),(5,6)}

The set of ordered pairs shown below defines a relation. {(0,0),(1,5),(2,8),(3,9),(4,8),(5,5),(6,0)} What is the value of the greatest element in the range of this relation?

Identify each graph below as a function or just a relation.

Find the slope of each line below.

Find the slope of the line through (9, 4) and (0, 5).

Find the slope of the line through (4,6) and (4,10).

Find the slope of the line through (4,6) and (5,6).
