Answer:
5/7 and -7/5
Step-by-step explanation:
slope is - 7/5
if line is written as Ax + By + C = 0
the slope is -A/B
if you work that equation you have
By = - Ax - C
y = (-A/B) × x - C/B
and term multiplying the x is the slope in case you had doubts about the - A/B
the multiplication of the slopes of 2 lines that are perpendicular is - 1
x × -7/5 = -1
x = 5/7
the slope of 2 lines that are parallels is the same, so slope = -7/5
