y = 8 is a horizontal line, the line is perpendicualr to a vertical line, get it?

so 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?

well how did you get x=4?

it said that it has to contain (4, 1) so that's how I figured that x has to equal 4

Some points of x = 4 are: (4,2)(4,8),(4,6).......so one....understand?

so you just took the 4 from the pair?

yup, if i included another xvalue along with the pair we have, its not going to be perpendicular, that's why
