<span>The numbers of beads on 500 handcrafted bead necklaces follow a normal distribution whose mean is 24 beads and standard deviation is 4 beads.
</span>so....

B. Parallel
Step-by-step explanation:
Equation 1 simplified: y = 3x+7

But we also see the slopes of the equations are opposite and negative to each other. Making the lines perpendicular.
