9. You own k shares of a stock that is selling for x dollars per share. The quarterly dividend is y dollars per share.
a. Express the annual dividend for one share algebraically.
b. Express the annual dividend for all k shares algebraically.
c. Express the yield as an algebraic fraction.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
