# Is -4 the same as 1/4 in graphs?

Notice that `1/4` is equal to `0.25` , hence, you should compare the values 0.25 and -4. It is easy to see that the values are not equal, hence, they correspond to different points on the graph.

Hence, you should consider as example the linear function `f(x) = 4x + 1` and you should substitute `1/4` for x such that:

`f(1/4) = 4*(1/4) + 1 => f(1/4) = 2`

You should substitute -4 for x such that:

`f(-4) = -16 + 1 = -15`

Notice that the y coordinate at `x = 1/4` is y=2 and at x = -4 is y = -15 are different, hence `(1/4,2)` and `(-4,-15)` represent two different points.

**Hence, to avoid any further confusions `4^(-1) = 1/4` and `-4!=1/4` , hence, the points whose coordinates are -4 and `1/4` represent different points.**
