We have to graph the line y = -2/5*x-5.

To do that, we need two points that belong to the line.

We can give two arbitrary values to x and calculate y using the equation of the line.

For example, for x=0, we get:


x=0\Rightarrow y(0)=-(2)/(5)\cdot0-5=-5

Then, the point is (0,-5).

Now, if we make x = 5, we can calculate y as:


x=5\Rightarrow y(5)=-(2)/(5)\cdot5-5=-2-5=-7

Then, we get the point (5, -7).

Using this two points we can graph the line as:

NOTE: In the case that the graph is limited to certain intervals in x or y, we have to try with different values of x until we find two points within the range shown by the graph.

In this case, (0,-5) and (5,-7) will be located within the range shown.
