so the vertical will be 1 and horizontal will be 4

amoodarya · Answer

x=1 , y=4 
vertical line is in form of x=a 
horizontal line  is in form of y=b

skullpatrol · Answer

The reason why you write x = 1 for your answer to the equation of a vertical line is that x can only be replaced by the number 1 to make the equation x = 1 the true statement: 1 = 1. On the other hand, the  y value maybe replaced by any number denoted by "y."

The answer can now be abbreviated by the ordered pair ( 1 , y ) for any point on the vertical line satisfying the equation: x = 1.

skullpatrol · Answer

Exactly the same reasoning would be used for y = 4, or ( x , 4 ) for the horizontal line.
