• -4
• 4
• 1/4
• -1/4

What is the equation of this line?

• y = 2x +2
• y = 2x -2
• y = -x + 2
• Cannot be Determined

Write the following equation in slope-intercept form:
4x - 3y = 12

• y = -4/3x + 3
• y = -4x + 12
• y = 4/3x - 4
• y = 4/3x - 12

Write an equation  
m = 5 through (-1, -3)

• y = 5x + 2
• y = -5x - 5
• y = -5x + 2
• y = 2x - 5

Write the equation of the line PARALLEL to the line y = 4x - 9 that passes through the point (-2, 4)

• y = 4x + 12

• y = -4x -4

• y = -1/4x + 5/2

Write the equation of a line PERPENDICULAR to the line y = 3x + 2 that passes through the point (9, -2)

• y = -1/3x - 5

• y = 3x-29

• y = 1/3x -5

• y = -1/3x +1

Solve the system by substitution.
