Best ResponseYou've already chosen the best response.0I tried \[yy _{1}=m(xx _{1})\] but i would always get a value for y which isnt right

Best ResponseYou've already chosen the best response.1I think it is x = 4, thats the equation

Best ResponseYou've already chosen the best response.1y = 8 is a horizontal line, the line is perpendicualr to a vertical line, get it?

Best ResponseYou've already chosen the best response.1so with a vertical line, x will equal one number, in this case, it is 4, always 4 for any y, so its x = 4, did i confuse u?

Best ResponseYou've already chosen the best response.0well how did you get x=4?

Best ResponseYou've already chosen the best response.1it said that it has to contain (4, 1) so that's how I figured that x has to equal 4

Best ResponseYou've already chosen the best response.1Some points of x = 4 are: (4,2)(4,8),(4,6).......so one....understand?

Best ResponseYou've already chosen the best response.0so you just took the 4 from the pair?

Best ResponseYou've already chosen the best response.1yup, if i included another xvalue along with the pair we have, its not going to be perpendicular, that's why
