How do you find a standard form equation for the line with (7,3); perpendicular to the line y = 4x +2?
In general, when two lines
The given equation of the line
is in slope-intercept form
This means that the slope of the line is
Hence, the slope of the line perpendicular to the given line is
To get the y-intercept, simply substitute the coordinate of the point which we know is on the line
Hence, the equation of the line is
