Question

How do you graph `y=-x+2` by plotting points?

Answer 1

`(0,2) (1, 1) ( 2, 0) ........`

Explanation:

`y = - x + 2`

Choose x-values and use the given equation to work out y-values.
if...
`x = 0, y = 2 rarr ( 0 , 2)`
`x = 1, y = 1 rarr ( 1, 1 )`
`x = 2, y = 0 rarr ( 2 , 0)`

so plot the points `(0,2), (1, 1), ( 2, 0)` on a grid and join them with a straight line.
graph{-x+2 [-10, 10, -5, 5]}
