low the axis of x. If — 2.5 < x < 1, both factors are positive; thereforey > 0, and the corresponding part of the curvelies above the axis of x. Finally, if x > 1, wehave the same result as when — 2.5 < x < 1, andthe curve does not cross the axis of x at thepoint x = 1 but is… … Ax + By+ C=Q, Fig. 23 always represents a straight line, and since a straight line isdetermined by two points, it is generally sufficient in plottingan equation of the first degree to find the intercepts on thetwo axes and draw a straight line through the two points thusdetermined.
