Pre Calc: Write an equation of the line perpendicular to the graph of x = 3 and passing through D(4, –1).
\(x=3\) is vertical, so your line is horizontal horizontal line looks like \(y=\text{some number}\) in your case that number is \(-1\)
@satellite73 okay, how do I find a slope of x=3 to right a perpendicular equation?
The slope of a line like"---" is zero. The slope of a line like" | " is undefined.
@saifoo.khan thanks a bunch <3
