The equation x = -8 contains the two points (-8 , -3) and (-8 , 1) ⇒ 2nd answer

Step-by-step explanation:

Let us revise the equations of the horizontal and vertical lines

  • The equation of a horizontal line passes through point (a , b) is y = b, because all points lie on the line have the same y-coordinate b
  • If a line passes through two points have the same y-coordinates, then the line is horizontal
  • The equation of a vertical line passes through point (a , b) is x = a, because all points lie on the line have the same x-coordinate a
  • If a line passes through two points have the same x-coordinates, then the line is vertical

∵ The line contained the two points (-8 , -3) and (-8 , 1)

∵ The two points have the same x-coordinate = -8

- From the 4th note above

∴ The line is vertical

∵ The equation of a vertical line is x = the x-coordinate of any point

   on the line

∵ The x-coordinate of the points on the line = -8

∴ The equation of the line is x = -8

The equation x = -8 contains the two points (-8 , -3) and (-8 , 1)
