What is the equation of the line perpendicular to #y=-2/21x # that passes through # (-1,6) #?
The slope of a perpendicular line is the negative reciprocal of the original line.
The slope of the perpendicular line is
Now we can use point slope form to plug in the point, the slope abs find the slope intercept form equation.
The point (-1,6) is
Hopefully this helps!
Compare to the standard form of
In your equation
We know that this new line passes through
So substitute into equation (2) the values
The line perpendicular to that given is:
