Answer:
Neither
Step-by-step explanation:
suppose that y = -2/5x+3 <=> y= ax+b and y=2/5x +7 <=> y=a'x+b'
so we have: a = -2/5; a'= 2/5
b= 3; b'=7
- 2 lines parallel when : a=a' and b not equal b'
- 2 lines perpendicular when: a * a' = -1
By the following things, 2 lines are not parallel or perpendicular.
