Answer:
-4/5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-10-(-2))/(9-(-1))
m=(-10+2)/(9+1)
m=-8/10
simplify
m=-4/5
Option D:
The solution to the equation is y = 27.
Solution:
Given equation:
![$\frac{1}{3} y=9](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B3%7D%20y%3D9)
To solve this equation:
![$\frac{1}{3} y=9](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B3%7D%20y%3D9)
Multiply by 3 on both sides of the equation.
![$3 \times \frac{1}{3} y=9 \times 3](https://tex.z-dn.net/?f=%243%20%5Ctimes%20%5Cfrac%7B1%7D%7B3%7D%20y%3D9%20%5Ctimes%203)
3 in the numerator and denominator get canceled.
y = 9 × 3
y = 27
The solution to the equation is y = 27.
Option D is the correct answer.
