Answer:
y = x + 15
Step-by-step explanation:
Find the slope(m) of the line that passes through (2, 17) and (6, 21):
m = 1
Find the y-intercept (b) by substituting x = 2, y = 17, and m = 1 into y = mx + b
Thus:
17 = 1(2) + b
17 = 2 + b
17 - 2 = b
15 = b
b = 15
To write the linear function rule, substitute m = 1 and b = 15 into y = mx + b.
Thus:
y = 1(x) + 15
y = x + 15
Answer:

Answer:
(D) Each year,the machinery loses a value of 4,500
When it is 3 years old,it is worth a little over 35K ,and when it is 6 years old,its worth about 22K.
This info means A,C and B is wrong b/c it loses too little value per year.
This is short cut for this type of questions, ie, gain or loss square/100=5^2/100=>0.25%loss
Always this type of questions will have loss
