I can do parallel lines, but not perpendicular
find the equation of the straight line in form ax + by + c = o which:
passes through (1,4) and is perpendicular to 5y = x + 2
thanks
First we need the gradient f the line:
Therefore we now know the gradient of the given line is 1/5.
So the gradient of the perpendicular line must be -5.
Putting this into the equation of the line we are finding, we get:
is the y intercept, which is what we will need to find.
Now, we just need to put the coordinates into the equation to find .
We now have our equation
(can also be written as: )
