Roger bought 800 shares of a company's stock for $15.34/share. He pays a broker a commission of $20 to buy or sell stock. After one year, Roger sold all his shares, when they were worth $18.77/share. How much did it cost to buy the stock? What is the net gain or loss? What was the rate of return?

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
