What is the equation in slope-intercept form of the line that crosses through the point and is perpendicular to the line represented by ?

Answer 1

y - y1 = m(x- x1) is slope intercept form. for point (x, y) where the slope is m

If you have a perpendicular slope it is a negative reciprocal. if we have m above, we would have -1/m for perpendicular slope.

y - y1 = -1/m (x - x1)
