Math video on how to write the vector equation of a line given its slope and one point on the line. Eqxxtyyt eq to determine the the slope of the tangent line definite by the angle. Hence its direction vector is 𝑞 𝑝.
See full answer below.
We indicate this graphically by inserting a small line segment at the point 1-1 of slope 2. A normal vector is. The slopes called direction cosines on the x y x z and y z planes are then. To find the slope of an equation given in ymxb balance the equation until y is by itself without any constants.
