Question

How do you find five ordered pairs of `y=-x+3`?

Answer 1

Five ordered pair are `(-7,10), (-2,5), (3,0), (9,-6)` and `(11,-8)`

Explanation:

Select any five values at random for `x`. Let these be `{-7,-2,3,9,11}`

Corresponding values of `y` are given by `y=-x+3` and hence these are

`{-(-7)+3,-(-2)+3,-3+3,-9+3,-11+3}` i.e.

`{10,5,0,-6,-8}`

An hence five ordered pair are

`(-7,10), (-2,5), (3,0), (9,-6), (11,-8)`
