Answer:
y=-3
Step-by-step explanation:
First, you want the slope.
The slope is

0/-8 = 0, so the line is horizontal.
the y-intercept must be -3 because it never changes.
So the equation must be
y=-3
In a given radioactive nuclide, we can easily find the mass number, mass of proton and neutron by subtracting the mass of proton from the mass number. The mass number, mass of proton and mass of neutron of the radioactive nuclide are 131, 56 and 75 respectively.
<h3>Properties of an atom</h3>
Data;
- Mass Number = 131
- Atomic Number = 56
In a given atom, the mass number of an atom comprises of the mass of proton and mass of neutron. The atomic number of the element or atom is equal to the mass of the proton.
In this case,
mass number = mass of proton + mass of neutron.

From the calculation above, the mass number, mass of proton and mass of neutron of the radioactive nuclide are 131, 56 and 75 respectively.

So, we have 2 canoes with teams. They are both at a constant speed of 6mph, but one of them is 2mi ahead.
Assuming
and
,we express that as:
Team A = 
Team B = 
Because of those 2 extra miles and both canoes travelling at the same constant speed, they will never reach one another, like you correctly answered below.
