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?
