Answer:
The constant of proportionality is 0.3, or K=0.3.
Step-by-step explanation:
The chart I attached shows points that are plotted on the proportional line. In order to find the constant of proportionality from these points, you have to divide the amount of change by the number of years. For example, 3 divided by 10 or 6 divided by 20. This results in 0.3, which means that every year, there is 0.3 centimeters of change in the sea level.

14a+3b-6=0
a=24/49, b=-2/7

Answer:
Step-by-step explanation:
6) the answer is option b
y = - x + 3
x - y = 1
From the graph, the point at which the lines of the two equations meet is the solution to the system of equations
The points = x = 2 and y = 1
If you substitute these values in option b, it satisfies the equations.
7) the correct option is d
-x + y = -3 - - - - - - -1
2x -y = 6 - - - - - - 2
If we solve using elimination method,
Multiply equation 1 by 2 and equation 2 by 1
-2x + 2y = -6
2x -y = 6
Adding both equations
y = 0 and substituting y = 0 in equation 2,
x = 3
So y = 0 and x = 3
So it has only one solution
8) The lines of the two equations meet at a point where x = 3 and y = 0
Option d is the correct answer
-x +y = -3
2x - y = 6
Substituting x = 3 and y = 0 in option d,
- 3 + 0 = -3
6 - 0 = 6
9) y = x-2
x = 17-4y
Substituting y = x - 2 in x = 17 - 4y, we have
x = 17 -4(x - 2)
Opening the bracket
x = 17 - 4x + 8
x + 4x = 17 + 8
5x = 25
x = 25/5 = 5
