How do you find a standard form equation for the line Perpendicular to the line 7x+y=49; contains the point (7,-1)?
their respective slopes
In the given equation, we have
Now, the equation of the perpendicular line will be something like
To get the y-intercept, simply substitute the coordinates of the point which we know to lie on the line
Hence, the equation of the perpendicular line is
or, in standard form
