Question

How do you graph `y=2x-4`?

Answer 1

Try different x values and find y. Plot accordingly.

Explanation:

If `x=-2`, your function `y=-8`
If `x=-1`, your function `y=-6`
If `x=0`, your function `y=-4`
If `x=1`, your function `y=-2`
If `x=2`, your function `y=0`
If `x=3`, your function `y=2`. It goes and goes......
