FIND THE FUNCTION RULE x: -2, -1, 0, 1 , 2 y: 9 , 4, -1, -6, -11

looks like for every increase of 1 in the x, our y decreases by 5

so it must be
y = -5x + c
all we need is to find c

pick one of the data values:
0 = 0, y = -1

-1 = 0 + c
c = -1

y = -5x - 1

thx

what is c mean?????

C means x!!!!!!!!

what does "c" mean?
