What is the general form of the equation of the line shown?

a)x + y = 0

b)x - y = 0

c)-x - y = 0

  B)  x - y = 0

Step-by-step explanation:

The equation for the line shown is y=x. This can be written in general form by subtracting y:

  x - y = 0

General form for the equation of a line is ...

  ax +by +c = 0

where a, b, c are preferred to be mutually prime integers and a ≥ 0. If a = 0, then b ≥ 0.

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
