    I tried \[y-y _{1}=m(x-x _{1})\] but i would always get a value for y which isnt right

    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?

    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?

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