Question

PLEASE ANSWERRRRRRRRRRRRRRRRRRRRRRRR

Answer 1

Answer:

a=11, b=53

Step-by-step explanation:

y=ax+b

x=1, y=64 -> 64=a+b

x=2, y=75 -> 75=2a+b

75-64=a, a=11, b=53

All the other points obey this rule.

Answer 2

Answer: y = 1x + 16

Step-by-step explanation:

Each time 1 goes up to 2, 64 goes up 16 going to 75, then going to 3, add 16 to 75, adds up to 86 and so on
