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
First find the slope
Slope formula: (y2-y1)/(x2-x1)
(-4-(-6))/(-2-2) = 2/-4 = -1/2
Slope intercept formula: y = mx + b
Y = -1/2x + b (solve for b)
Plug in any point
-6 = -1/2(2) + b
-6 = -1 + b, b = -5
Solution: y = -1/2x - 5
The stick of a broom could be the same length as a baseball bat
60/30 as a mixed # is 2/1 or 2
The sign needed to be added is x.
