Answer:

The answer is No .

Explanation:

In order to prove it, you can substitute x-coordinate or y-coordinate into the equation :

Let x = -1,

[tex]y = 5( - 1) + 3 \\ y = - 5 + 3 \\ y = - 2[/tex]

OR,

Let y = -1,

[tex] - 1 = 5x + 3 \\ - 4 = 5x \\ x = - \frac{4}{5} [/tex]

Therefore, (-1,-1) does not lies on the line.
