Answer:
3/4
Step-by-step explanation:
Constant of Proportionality is just a fancy way of saying slope (for a line passing through (0, 0), at least).
You can find it by looking at y/x, which will be equal at any point on the line (which is why it is a "constant").
So, for multiple points on the line:
1.5 / 2 = 3/4
3 / 4 = 3/4
4.5 / 6 = 3/4
X= -2
look at the 6x-12 you divide -12 by 6 and get x=-2
The y intercept is 2.25 and x intercept is -3
Y : x
14 : 18
31 : x
18*31/14=x
39.85714286
ANSWER
x=39.86
