Use the table below for f(x) to determine the average rate of change from f(4) to f(5).
x g(x)
4 -16
5 -23
6 -28
7-31
8 -32
9-31
10-28
11 -23
12 -16

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
