Question

Find the equation of the line that is perpendicular to the line x=1 and contains the point (-2,9).

Answer 1

what is the slope relationships with perpendicular lines?

Answer 2

what is the slope to x = 1 (very simple - dont think too hard on this)

Answer 3

Opposite reciprocals

Answer 4

So would the slope be zero?

Answer 5

hint: x = 1 is a vertical line

Answer 6

yes

Answer 7

so with m =0
perpendicular m = 0
so with point (-2,9) what is the new line...

if you can see it great
if not use y -y1 = m(x-x1)

Answer 8

Thanks! I just confused myself and wasn't sure :)
