Web1) You solve the original line equation for y if it isn't already. 2) The perpendicular line to that will be the most direct route to your point. Just take the negative inverse (if your line has a slope of 2, the negative inverse is -1/2). Which will be the slope of your perpendicular line. WebThe rule states that if the nonzero terms of a single-variable polynomial with real coefficients are ordered by descending variable exponent, then the number of positive roots of the polynomial is either equal to the number of sign changes between consecutive (nonzero) coefficients, or is less than it by an even number.
