Answer:
y=-12/11
Step-by-step explanation:
y-(-12/11)=0(x-(-12/13))
y+12/11=0(x+12/13)
y+12/11=0
y=-12/11
Since the slope equals 0, then the line is horizontal.

Answer:
y = 85°
z = 35°
x = 60°
Step-by-step explanation:
y) 180 - 120 = 60, therefore:
180 - (35 + 60)
=> <u>y = 85</u>
z) 
=> <u>z = 35</u>
x) 
180 - (35 + 85) 
=> <u>x = 60</u>
