Question

Does the point (-1,-1) lie on the liney = 5x + 3?​

Answer 1

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,

$y = 5( - 1) + 3 \\ y = - 5 + 3 \\ y = - 2$

OR,

Let y = -1,

$- 1 = 5x + 3 \\ - 4 = 5x \\ x = - \frac{4}{5}$

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