ACT Math : How to find the equation of a perpendicular line
Parallel and Perpendicular Line Calculator - eMathHelp
Students are often asked to find the equation of a line that is parallel to another line and that passes through a point. Watch the video tutorial below to understand how to do these problems and, if you want, download this free worksheet if you want some extra practice. Many students are more comfortable using slope intercept form but this kind of problem is actually much easier, using point slope form shown immediately below. If you're comfortable with point slope form , this is the way to go! Just look how little work there is to do! In fact, all that you have to do is substitute twice!
How do you write the standard form of the equation through: (3,1), perpendicular to y=-2/3x+4?

If we know the equation of a line, we can use what we know about slope to write the equation of a line that is either parallel or perpendicular to the given line. We know that the slope of the line formed by the function is 3. We also know that the y- intercept is 0, 1. Any other line with a slope of 3 will be parallel to f x. So the lines formed by all of the following functions will be parallel to f x.
