Best ResponseYou've already chosen the best response.4Horizontal line is in the form of \(y=a\). Saying, that all of the ycoordinates are going to be "a". ((And xcoordinates can be whatever you want.)) So if I wanted to find an equation of a horizontal line that passes through the point \((4,9)\), then my equation would be: \(\color{blue}{y=9}\).

Best ResponseYou've already chosen the best response.0so the answer would be 10 then right?

Best ResponseYou've already chosen the best response.4yes, y=10 would be your answer.

Best ResponseYou've already chosen the best response.4And same way, the equation of the vertical line is \(x=a\). Saying, that all of the \(x\)coordinates are going to be "a". ((And \(y\)coordinates can be whatever you want.)) So if I wanted to find an equation of a vertical line that passes through the point \((3,6)\), then my equation would be: \(\color{blue}{x=3}\).
