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? Could ANYBODY help out :'c

Answer 1

coordinate points come in the form of
(x,y)

for the line x=5
means all coordinate points on that line x=5

so you make up 2 random y values

Answer 2

2 coordinates on line x =5 is (5,5) and (5,1). X-coordinate will remain constant
Similarly on line y = -2 is (1,-2) and (2,-2).y- coordinate constant
Horizontal line means y- coordinate constant : y = -8
Vertical line means x - coordinate constant : x = 3
Line x = 4 is vertical and its slope is 90 degrees.
Line y = -8 is horizontal and its slope is 0 degrees.
