Therefore, the x and y coordinates of a point are called the ------------------Cartesian coordinates of the point rectangular Two vectors a- and b- are said to be --------------if they have the same magnitude and direction. equal ____________ have magnitude and direction but have no particular position associated with them, for example; displacement. Free vectors A ---------------is the locus of a curve (equidistant from a point) circle The slope of a straight line can be defined in respect to the angle of inclination of the line with the------------------- x-axis A____________ is a succession of numbers of which each number is formed according to a definite law which is the same throughout series
