What is the equation of the line parallel to y = 3 that passes through the point (-2, 1)?

• x = 1

• x = -2

• y = 1

• y = -2

Why is the line parallel to y = 3 also a horizontal line?

• Because it is a vertical line

• Because it passes through the origin

• Because it has the same slope and never intersects

• Because it has the same y-intercept

What is the y-coordinate of the point through which the parallel line passes?

• 3

• 0

• 2

• 1

What is the slope of a horizontal line?

• Undefined

• Zero

• Positive
