The graph shows the first quadrant portion of four exponential functions. if the equation of the blue curve is y = ab-x, then the equation of the green curve is
a) y = ab-x
b) y = 0.5ab-x
c) y = a(0.5bx)
d) y = ab-x - 0.5

Which lines are parallel? justify your answer. lines p and q are parallel because same side interior angles are congruent. lines p and q are parallel because alternate exterior angles are congruent lines l and m are parallel because same side interior angles are supplementary lines l and m are parallel because alternate interior angles are supplementary.
