Which equation represents the vertical line passing through point (-6,4)

Question

^{Here are the given equations} 

y=-6

y=4

x=4

x+2=-6

x=-6

Answer 1

Hi Billy, the y equations represent a horizontal line and can be discarded. The x values represent vertical lines. For a vertical line to go through the point (-6, 4) it will have to have an equation that equates to x = -6.

 

Therefore, x = 4 will not work, and x + 2 - 6 equates to x = -4, and it will not work.

 

Solution: x = -6.
