Question 1092827: Write the equation of the line perpendicular to 3y -x = 2 and passing through (9, -10) Found 2 solutions by MathLover1, MathTherapy:Answer by MathLover1(20849) (Show Source):
You can put this solution on YOUR website! Write the equation of the line perpendicular to and passing through (, ):
the equation of the line is: where is a slope and is y-intercept
if given , first find a slope
->
the line perpendicular to given line must have a slope equal to negative reciprocal of , and it is
so far your equation is
to find use given point (, )
and of the line perpendicular to is:
To obtain the equation of a line that's perpendicular to another, we do the following: 1) Put GIVEN equation in STANDARD form 2) Switch coefficients on variables, and change the constant to z 3) Negate y 4) Substitute GIVEN point to determine z
These steps should lead you to the required equation:
