Question

The table shows ordered pairs of the function y=8-2x when x=8, the value of y is?

Answer 1

y=8-2×
y=8-2(8)
y=8-16
y=-8

Answer 2

ANSWER

When

`x = 8`

`y = - 8`

Step-by-step explanation


The ordered pair in the table were generated with the function,

`y = 8 - 2x`


To find the value that corresponds to

`x = 8`

We substitute 8 in to the given function and simplify.



We obtain,


`y = 8 - 2(8)`

Let us multiply to obtain,


`y = 8 - 16`



We now simplify to get,

`y = - 8`


Therefore when x is 8 the value of y is -8.
