write a function rule for the table.
Y=
x -9, -7,-4, 3, 11
y 27, 23, 17, 3, -13
I am trying to help my son with home school work. I have no idea how to do this. Someone please help! I would love for someone to work the problem out step by step, so I can learn to work the problem out myself.
check the slope of each segment.
(23-27)/(-7+9) = -2
(17-23)/(-4+7) = -2
(3-17)/(3+4) = -2
(-13-3)/(11-3) = -2
So it appears that y = -2x + c
Since -2(-9) = 18 but y(-9) = 27, c=9
y = 9-2x
