Question

I could really use some help understanding how to do this.. please and thanks! Model the function rule y = -2x - 3 with a table of values

Answer 1

Plug in x = 0

y = -2x - 3

y = -2(0) - 3

y = 0 - 3

y = -3

So when x = 0, y = -3

------------------------------

Plug in x = 1

y = -2x - 3

y = -2(1) - 3

y = -2 - 3

y = -5

So when x = 1, y = -5

------------------------------

Plug in x = 2

y = -2x - 3

y = -2(2) - 3

y = -4 - 3

y = -7

So when x = 2, y = -7

------------------------------

Plug in x = 3

y = -2x - 3

y = -2(3) - 3

y = -6 - 3

y = -9

So when x = 3, y = -9

------------------------------

Plug in x = 4

y = -2x - 3

y = -2(4) - 3

y = -8 - 3

y = -11

So when x = 4, y = -11

------------------------------

Plug in x = 5

y = -2x - 3

y = -2(5) - 3

y = -10 - 3

y = -13

So when x = 5, y = -13

------------------------------

Answer 2

So we get the table of values


x y
-----------------------
0 -3
1 -5
2 -7
3 -9
4 -11
5 -13
