Answer is C and D.
Reasoning: If you convert all equations into form y=mx + c where m is slope and c is the intercept, you can see that only c) y=x+4 has the slope (m) as positive (which is D in second part)

It’s b; both a and b are the basically the same equation so neither one will work and all of them are in standard form so c won’t work
