Answer:
The proportional relationship would be y = 2x and another point would be C. (5, 10)
Explanation:
In order to find this, use the proportional relationship equation.
y = kx
Now input the values given at the beginning.
26 = k(13)
And solve for k
2 = k
Now we can model the equation.
y = 2x
And then we can check for which other values it would work with. C is the answer.
10 = (2)(5)
10 = 10
