Solving Linear Function

Write the equation of the line parallel to the x-axis that passes through the point (5,1). What is the slope of this line?

• y=1; undefined

• y=1; zero

• y=5; zero

• x=5; undefined

Write the equation of the line perpendicular to the x-axis that passes through the point (4, -3). What is the slope of this line?

• x = 4; undefined

• x = -3; undefined

• y = 4; zero

• x = -3; zero

Which inequality can be represented by the graph?

• y ≤ 2x

• y ≤ 2x - 1

• y ≥ 2x - 1

• y < 2x - 1
