The following is a function that is positive in domain:

Find the equation daxis iscribing the line.
Which equation represents a line that is positive in domain for each value of x.
To find out if the equation intersects the x-axis, we need to substitute y=0 in each equation.
If the function has a solution where y=0 then the equation has an intersection point and is not the correct answer.
Let's start with the first equation:
y = 3x+8
We will substitute as instructed:
0 = 3x+8
3x = -8
x = -8/3
Although the result here is not a "nice" number, we see that we are able to arrive at a result and therefore this answer is rejected.
Let's move on to the second equation:
y = 300x+50
Here too we will substitute:
0 = 300x + 50
-50 = 300x
-50/300 = x
-1/6 = x
In this exercise too we managed to arrive at a result and therefore the answer is rejected.
Let's move on to answer C:
y = 3
We will substitute:
0 = 3
We see that here an impossible result is obtained because 0 can never be equal to 3.
Therefore, we understand that the equation in answer C is the one that does not intersect the x-axis, and is in fact positive all the time.
Therefore answer D is also rejected, and only answer C is correct.
