PEMDAS
since we don't have exponentes or paretnahsees we do
muliplictaion or division whichever comes first (since division is just multiplication of a fraction)
addition or subtraction whichever comes first (since subtraction is adding a negative)
so
multiply/divide
0 times 3=0
9/3=3
now we have
5-0+3
add/subtract
5-0=5
5+3=8
answer is 8
Typically if it is a linear function then it doesn't matter. However if it is a quadratic, cubic, and so on and so forth....(

) you may want to used the distance formula if you are not given any other points (with the exception of the vertex, asymptote or roots... etc).
Hey There!
The formula of the general form equation is
0 = Ax + By + C
As we look at the answer choices we see that the last choice best represents the correct answer.
x + y + 2 = 0
Best matches the formula given and therefore that would be the correct answer.
Thus, the answer would be x + y + 2 = 0
