Answer:
option b
Step-by-step explanation:
![{x}^{2} - 2x - 15](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%202x%20-%2015)
![{x}^{2} - 5x + 3x - 15 = 0](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%205x%20%2B%203x%20-%2015%20%3D%200)
![x(x - 5) + 3(x - 5) = 0](https://tex.z-dn.net/?f=%20x%28x%20-%205%29%20%2B%203%28x%20-%205%29%20%3D%200)
![(x - 5)(x + 3) = 0](https://tex.z-dn.net/?f=%28x%20-%205%29%28x%20%2B%203%29%20%3D%200)
x = -3 (Not possible)
x = 5
So, x = 5

Answer:
y = 3x + 23 and
![y = \frac{1}{3}x + 2](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B1%7D%7B3%7Dx%20%2B%202)
Step-by-step explanation:
The first equation is 9x - 3y = - 69 and we have to write it in slope-intercept form.
Now, 9x - 3y = - 69
⇒ 3x - y = - 23 {Dividing both sides by 3}
⇒ 3x + 23 = y
⇒ y = 3x + 23 {Interchanging the sides} (Answer)
The second equation is x - 3y = - 6 and we have to write it in slope-intercept form.
Now, x - 3y = - 6
⇒ x + 6 = 3y
⇒ 3y = x + 6 {Interchanging the sides}
⇒
{Dividing both sides by 3}
⇒
