Answer:
Should be 60°
Step-by-step explanation:
Since each interior angle in an octagon is 120°, you would subtract 120° from 180° (which is the angle of a line). This would get you 60 °.
Make it into slope intercept form
-3y = -12x + 3
Y = 4x - 1
Perpendicular = opposite sign and reciprocal
Parallel: same slope
Perpendicular: y = -1/4x
Parallel: y = 4x
I graphed it on desmos, hope this helps a little :)

You would make two mountains because you need to compare the two factor mountains
