Answer
Given,
proton represent positive charge
the integer that will give the representation of 5 protons will be equal to + 5
an electron represents negative charge
the integer that will give the representation of 3 electrons will be equal to -3
Answer:
x=1 and y=5
Step-by-step explanation:
Let's solve for the answer to determine if it is rational.

it is a rational number.
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx
so
That means it's the equation of a line passing through the origin.
case a) and case d) are discarded because the line does not pass through the origin
<u>case b) we have</u>
for x=2 y=4
y/x=k-------> 4/2=2------> k=2
y=2x-------> in this case the value of y is two times the value of x
<u>case c) we have</u>
for x=4 y=2
y/x=k-------> 2/4=1/2------> k=(1/2)
y=(1/2)x-------> in this case the value of y is one-half of the value of x
therefore
the solution is the case c) see the attached figure
