Question

Give the coordinates of two points on the line x = 5.
Give the coordinates of two points on the line y = -2.
Write the equation of the horizontal line passing through the point (-1, -8).
Write the equation of the vertical line passing through the point (3, 1).
Is the line with equation x = 4 horizontal or vertical? What is the slope of this line?
Is the line with equation y = -8 horizontal or vertical? What is the slope of this line?

Answer 1

Write the equation of the horizontal line passing through the point (-1, -8)
y = -8
Write the equation of the vertical line passing through the point (3, 1).
x = 3
Is the line with equation x = 4 horizontal or vertical? What is the slope of this line?
Vertical, unidentified

Is the line with equation y = -8 horizontal or vertical? What is the slope of this line?
Horizontal, zero

Answer 2

Give the coordinates of two points on the line x = 5.
(5, 2) (5, -3)

Give the coordinates of two points on the line y = -2.
(5, -2) (13, -2)
