An alternative line definition Given a fixed point P 0 ( x 0 , y 0 ) and a nonzero vector n = 〈 a , b 〉 the set of points P 〈 x , y 〉 for which P 0 P ⇀ is orthogonal to n is a line ℓ (see figure). The vector n is called a normal vector or a vector normal to ℓ. 69. Suppose a line is normal to n = 〈 5 , 3 〉 . What is the slope of the line?
