Do you know what the right answer is? I haven't done this stuff since high school. So, I could be wrong. I thought I'd warn you in advance. ;)
I am not sure if this is how you do the problem, but this is how I did it:
I plugged in x-values to each equation until I found the one that fit the graph. The shading I believe represents the side of the line that we would like to have a y-coordinate on. I attached a screenshot of my work. Hope it makes sense!

It's <span>Diophantine equation.
First, we need to found gcd(6,(-2)):</span>
6=2*3
(-2)=(-1)*2
So, gcd(6,-2)=2
Now, the question is. Can we dived c=24, by gcd(6,-2) and in the end get integer?
Yes we can.
So, we can solve it.
Now is the formula:
Second, we need the first pair (x0,y0)
if
x=0
then
Third, we gonna use that formula:
Congratulations! We solve it.
