Question

What is the function for
y = -2x + 9
X-4 -4 - 2 0 2 4 . 4 y|17 _ _ _ _​

Answer 1

When, X=-4

y=17

X= - 3 with y =15

X= - 2 with y =13

X= - 1 with y =11

X=0 with y=9

X=1 with y=7

X=2 with y=5

X=3 with y=3

X=4 with y=1

As co-ordinate it'll be:

(-4,17)

(-3,15)

(-2,13)

(-1,11)

(0,9)

(1, 7)

(2,5)

(3,3)

(4,1)
