Answer:
y = -5
Step-by-step explanation:
The coordinate point is in the format (x, y)
Therefore, the y-value of (4, -5) is -5
So the equation of the horizontal line is therefore y = -5
Your answer would be choice b
Answer:
The answer is 
Step-by-step explanation:
In order to determine the answer, we have to know about equation. In an equation, we have variables, some of them depend on the others. If we want to know the value of one variable ( the dependent variable), we have to free it in any side of the equation.
In this case, we want to know the value of "L" variable. So we free that variable to the right side of the equation.

We divide each side by "W":

We simplify the "W" in the right side:

Finally, the solution for "L" is :

If you call
the mass of the ant and
the load, we have the equation

In fact, the mass of the ant is one tenth of the load, which is exactly what this equation states.
Since we are given the load, we simply need to plug its value in the equation to deduce the mass of the ant:

<span> -4w+8+4w=2+2
</span><span> -4w + 8 +4w = 4
</span> -4w + 8 +4w - 8 = 4 - 8
0w = -4
