Answer:
2x + 120 = 180 (being co interior angle)
or, 2x = 180 - 120
or, 2x = 60
or, x = 60/2
or, x = 30
therefore 2x = 2* x = 2* 30= 60

Step-by-step explanation:
Answer: y+4=-1/3(x)
Step-by-step explanation:
y-y1=m(x-x1) (Formula)
Y-intercept -4 so point is (0,-4)
m or slope=-1/3
y--4=-1/3(x-0)
y+4=-1/3(x)
