P=2l+2w
150(2)+170(2)
300+340
640 m
Answer:
A
5/2 for line 1
5/2 for line 2
5/2 for line 3
B they are all parallel because the have equal slope
Step-by-step explanation:
explanation is in the image
that's all...have fun
Y=x is the answer alone, since it only crosses the origin
Standard form of a line is Y=mX+b
where m is slope
4x+2y=-6
2y=-4x-6
y=- 2x - 6
m= - 2 and y intercept is b=-6
