Best ResponseYou've already chosen the best response.0Here's a way of thinking about the question. When you graph a "solution", you get where the graph(s) intersect, right? This is because the points of intersection is where the (x, y) satisfy the equal sign. When you had two nonparallel lines, you had one solution because they intersect at one point. However, if you only have one line, like here, and nothing else, all you have to do is find (x, y) combinations that satisfy the equation.

Best ResponseYou've already chosen the best response.0Ok, ignore my explanation up there then. You're trying to find yvalues that satisfy the equation 3y + 4 = 2. Do you remember how to solve an equation like this for a variable?

Best ResponseYou've already chosen the best response.0Ok, basically, you're trying to make the left side equal the right side. So, 3y + 4 has to equal 2, and you're trying to solve for what 'y' is to make this happen. The way you go about solving this is to do the opposite of order of operations. \[3y+4=2\]\[3y+4\color{red}{4}=2\color{red}{4}\]\[3y=6\]\[3y\color{red}{\div3}=6\color{red}{\div3}\]\[y=2\]Now, we can check to see if this answer makes sense by plugging it back in for y. \[3(2)+4=6+4=2\]Because we got 2, this yvalue is correct, and it is the only yvalue that works. If you look, we only got 1 yvalue, and the number of yvalues is the number of solutions you have.
