Question

How do you graph `y=1/2x-2` by plotting points?

Answer 1

See explanation.

Explanation:

To draw a linear function you only need 2 points so it is enough to substitute 2 values for `x` and calculate the value of `y`.

`f(0)=1/2*0-2=2`

`f(2)=1/2*2+2=1+2=3`

Now you have to draw a line passing through `(0,2)` and `(2,3)`.
