If you were to draw another line connecting the two top corners, you would make an equilateral triangle.
An equilateral triangle has 3 60 degree angles.
The angle = 60 degrees.
Y=mx+b
m=slope
b=y-intercept
y=-4x+b
Plug in the coordinate in place of x and y (-2,1)
1=-4(-2)+b
1=8+b
Subtract both sides by 8 to isolate B
b=-7
Final answer:

Answer:
Well, they both involve math, and a word problem uses a equation to tell the problem.
Step-by-step explanation:
Answer:
Parallel to line a: y=3x-2
Perpendicular: y= -1/3x-2
Neither: y=1/3x+1
Step-by-step explanation:
Parallel means that they have the same slope, which is 3x in line a. So y=3x-2 has the same slope as line a. Perpendicular means that it has the negative reciprocal, which of line a would be y= -1/3x-10. The remaining equation is for the last box, which is neither parallel or perpendicular.
