First Semester Review Algebra I

What is the x-intercept shown on the graph?

• (2, 0)

• (-2, 0)

• (0, 3)

• (3, 0)

• a
• b
• c
• d

• (1, -4)

• (1, 4)

• (-4, -7)

• (-7, -4)

Solve by elimination:
4x+9y=28
-4x-y=-28

• (-7,0)

• (6,0)

• (-6,0)

• (7,0)

Solve the system by multiplication.
3x + 2y = 16
7x + y = 19

• (-2,5)

• (-2,-5)

• (2,-5)

• (2,5)

Solve the system using Multiplication. 
2x + 3y = 12
5x - y = 13

• x = -3, y = -2

• x = 1.5, y = 2

• x = 6, y = 0

• x = 3, y = 2

Solve for z: 
8z - 22 = 3 ( 3z + 11) - z

• No Solution

• z = 0

• Identity

• z = 5

2x < -3x + 15

• x > 3

• x > 15

• x < 3

• x < 15

-1(2x + 4) ≥ 6

• x ≤ -5

• x ≥ -5

• x ≤ -1

• x ≥ -1

Find the slope of the line that passes through the points (2, 4) and (6, 12)

• 1/2

• -1/2

• 2

• -2
