Question

how do i write a function rule for this table where X is 2, 4, 6 and Y is 1, 0, -1

Answer 1

the differences look pretty constant, which would suggest a linear equation

Answer 2

y drops by 1 as x increase by 2 would suggest a slope of -1/2

Answer 3

y = -1/2 x

when y=0, x=4

0 = -4/2 , we need to "add" an adjustment; +2 should fit

y = -1/2 x + 2

Answer 4

thank you very much you are great!!! :)

Answer 5

lol, good luck
