  1. I already know how to do these. Try them yourself first and show me where you got stuck.

    The first three can all be done substituting in
    y = m x + b
    where m is the slope.

    For the fourth one, put the equation in form y = m x + b first
    Then find m' = -1/m
    That is the slope of a line perpendicular to the original one
    then do y = m'x + b and substitute in your point, which you forgot to type the y coordinate for.

    In the last one a circle equation is of form
    (x-k)^2 + (y-h)^2 = r^2
    where (k,h) is the center and r is the radius.

  2. y=mx+b

    26=3(6)+b
    b=26/18
    b=13/9
