Answer: The constant of proportionality is 1.5
Step-by-step explanation:
The equation for constant of proportionality is y=KX. the K stands for the constant of proportionality and since the constant proportionality is 1.5 you will take 1.5 * x and for example x is 2 so you do 1.5 * 2 and you get 3 and 3 is your y. If you plug in the equation you're saying 3 equals 1.5 * 2 which is right.
X-2 = 4+x
+2 +2
x = 6+x
-x -x
0 = 6

</span>3x + y = 9 (I)
3*(1) + y = 9
3 + y = 9
y = 9 - 3
