Answer:
Step-by-step explanation:
The value of the 4 in the thousand place is 10 times the value of the 4 in the hundreds place
The difference in salary is 36000-28000=8000
The difference in annual increase is 3000-2000=1000
Therefore it takes 8000/1000= 8 years to catch up.
At the end of eight years,
Salary with the first company = 28000+8*3000=52000
Salary with the second company = 36000+8*2000=52000
Slope or m is -2
Y intercept or b is (0,-1) or -1
