Question

Help me find the rate of change for these points listed here, and also write an equation:

(0 , 54)
(1 , x)
(2 , x)
(3 , 2)

(picture for table)​

Answer 1

54-2/0-3=-17,3=a
Y=-17,3x+54 b=54 because its the initial value of y when x =0
When x=1 y=36,7
When x=2 y=19,4
I juste replaced 1 in the equation and did the calculation with my calculator
