No, its extra information
Answer:
I believe the correct answer from the choices listed in the image is the second option. The statement that allows us to conclude that line m and line n are parallel would be that angle 2 and angle 7 are equal. They are alternate exterior angles. Hope this answers the question.
Since you are writing this in slope-intercept equation you will want to isolate the y. Therefore move the -8x over making it into -2y=8x+10. Then simply divide by the -2. And your equation will be y=-4x-5.
8a+4s=840
a=s+30
8(s+30)+4s=840
12s+240=840
12s=600
s=50
A=s+30
a=50+30
a=80
