Answer:
range = bigger number-smaller number
biggest number=166
smallest number=111
166-111
=55
Y = mx + b
slope(m) = 7
(5,30)...x = 5 and y = 30
now we sub and find b, the y int
30 = 7(5) + b
30 = 35 + b
30 - 35 = b
-5 = b
so ur equation is : y = 7x - 5 <==
Answer:14
Step-by-step explanation: minus *minus = + so its +27
