Question

How do you graph `y=-x+1` using a table of values?

Answer 1

Since this is a linear function you only need two values. You mark the two points and draw a line through them.

Explanation:

You may want to take the `x` values to cover the width of your intended graph, say `-5and+5`. Then:

`x_A=-5->y_A=-(-5)+1=+6->A(-5,+6)`

`x_B=+5->y_B=-5+1=-4->B(+5,-4)`

You then draw a line through `AandB`
