Answer:
the answer in the attached figure
Step-by-step explanation:
we know that
A relationship between two variables, a, and b, represent a proportional relationship if it can be expressed in the form
we're going to verify all the cases
Table A
![(3,9),(4,12),(5,20)](https://tex.z-dn.net/?f=%283%2C9%29%2C%284%2C12%29%2C%285%2C20%29)
The table A does not represent a proportional relationship
Table B
![(20,25),(24,30),(32,40)](https://tex.z-dn.net/?f=%2820%2C25%29%2C%2824%2C30%29%2C%2832%2C40%29)
The table B represents a proportional relationship between a and b
Table C
![(4,12),(5,15),(6,24)](https://tex.z-dn.net/?f=%284%2C12%29%2C%285%2C15%29%2C%286%2C24%29)
The table C does not represent a proportional relationship
Table D
![(3,4),(6,9),(12,16)](https://tex.z-dn.net/?f=%283%2C4%29%2C%286%2C9%29%2C%2812%2C16%29)
The table D does not represent a proportional relationship
therefore
the answer in the attached figure

Answer:
<h2>slope = 2</h2>
Step-by-step explanation:
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have
![(-3;\ -8)\to x_1=-3;\ y_1=-8\\(4;\ 6)\to x_2=4;\ y_2=6](https://tex.z-dn.net/?f=%28-3%3B%5C%20-8%29%5Cto%20x_1%3D-3%3B%5C%20y_1%3D-8%5C%5C%284%3B%5C%206%29%5Cto%20x_2%3D4%3B%5C%20y_2%3D6)
Substitute:
![m=\dfrac{6-(-8)}{4-(-3)}=\dfrac{6+8}{4+3}=\dfrac{14}{7}=2](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B6-%28-8%29%7D%7B4-%28-3%29%7D%3D%5Cdfrac%7B6%2B8%7D%7B4%2B3%7D%3D%5Cdfrac%7B14%7D%7B7%7D%3D2)
