Answer:
arlo
Step-by-step explanation:
if y=3 and x=4
then 3= -2(4)+5
3=(-8)+5
3=(3)
The equation has no X variable so whatever that adds up to becomes the y-intercept.
- 2/9 + 1/5 >> - 10/45 + 9/45 = - 1/45
Your y-int is - 1/45 or (0, - 1/45)

![\frac{4^3-2^2}{ \sqrt{81} - \sqrt{16}}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%5E3-2%5E2%7D%7B%20%5Csqrt%7B81%7D%20-%20%5Csqrt%7B16%7D%7D%20)
=
![\frac{64-4}{9-4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B64-4%7D%7B9-4%7D%20)
=
![\frac{60}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B60%7D%7B5%7D%20)
= 12
'B. 12' is the answer to question 2.
3. The answer to this question is 'B. No, because -1(-1) = 1'
