Answer:
13, 9, 5, 1
Explanation:
Put the value of x in the equation and do the arithmetic.
... y = -2(-2) +9 = 4+9 = 13 . . . . for x = -2
... y = -2(0) +9 = 0+9 = 9 . . . . for x = 0
... y = -2(2) +9 = -4+9 = 5 . . . . for x = 2
... y = -2(4) +9 = -8+9 = 1 . . . . for x = 4
____
It might have occurred to you that each increase of 2 in x will result in a decrease of 4 in y. Realizing this can save you some work.
