Answer:
D
Step-by-step explanation:
- The function of line goes through: (10,5) and (-15,5), has form of y =ax+b
- Then, we have 2 equations: 10 = 5a+b and -15 = -5a+b.
- Solve these two equations, we have a =2.5 and b = -2.5
So we have function of 2 lines:
y1 = 2.5x -2.5 and
y2 = 4/3x -2 ( derived from 4x-3y=6)
Rate of change of y1 is larger than y2 ( 2.5 >4/3)
y1 = 0
2.5x -2.5 =0, x = 1.
