Ответ:
Adding a negative number is just like subtracting the number: + (-14) = -14
so -23 + (-14) = -23-14
It's just like adding, but you add the (-) sign:
-23-14 = -37
Hope this helps! :D

They are parallel
Step-by-step explanation:
If that is a letter O in the second equation then they are parallel because you can plug in any number for it and if you plug in -0.9 for O then you can see they are parallel.
If that is the number 0 then they are neither parallel or perpendicular they make about a 25 degree angle with each other
