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)
