Answer:
Slope of a parallel line: 8
Slope of a perpendicular line: 
Step-by-step explanation:
A line parallel to another line has THE SAME slope.
So in this case, y = mx + b
M is the SLOPE
here,
y = 8x - 2
8 is m, the slope
So the parallel line has a slope of 8!
A perpendicular line is a line that intersects the line such that its vertical angles = 90 degrees, it looks like a +
Its slope is EXACTLY the opposite
so if the slope is 8, it is 1/8
BUT, it also is the opposite SIGN, so it becomes

That's all I can say for now! Hope this helps and a thank won't hurt! :)
