Answer:
Part 1) The slopes are negative reciprocals of one another.
Part 2) There is no relationship.
Explanation:
Part 1)
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
Part 2)
The y-intercept is the value of y when the value of x is equal to zero
Two linear functions that are perpendicular, could have the same y-intercept (the y-intercept would be the point of intersection between both lines)
so
There is no relationship
