Achess player played 20 games total. if he won 2 of the games, what is the ratio of games he lost to games he won?

So, we have useful information to answer this question. We know that he played 20 games and he won 2 games. To find the ratio of the games lost, we have to subtract the number of games played and the number of games won. 
20-2=18
So now we can find the ratio of games won and games lost
The answer is 18:2, 18 to 2, or 18/2.
You can also simplify the ratio to 9:1
So the final answer is 9:1

Hope this helped

C. i think it is step 3

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.
