Y=3x has a positive slope, and Y=-3x has a negative slope.
Add or subtract 360 degrees to find a coterminous angle. Since the questions wants you to find one between 0-360, you should subtract 360.

Answer:
2y=52
Step-by-step explanation:
1st equation *(-3) and 2nd *(2)
-6x-10y=34
6x+12y=18
eliminate -6x and 6x
add both equations
2y=52
-18+4x
2(2x-9)
4x=18
-4x=-18
x=18/4
-x=-18/4
